Lower-cost states ($123)MiddleHigher-cost states ($157)
What it shows: CA is the highest at $157 and AR the lowest at $123, across 51 states.
Counts below are complaints filed with NHTSA, not failure rates: a longer bar means more owners reported it.
Is your car affected?
What it shows: The most common band for complaints about this repair is under 50,000 (42%), against 60% for all complaints: the biggest difference between the two.
What it shows: The most common band for complaints about this repair is 3-5 years (43%). The biggest difference from all complaints is under 3 years old: 24% against 40%.
Is it urgent, and what do owners notice first?
1,212 owner complaints name this part.
Owners say the dealer could not fix or repeat the problem. If it comes back after a repair, ask what was tested before you pay again.
Which other parts do owners name in the same complaint?
Among the 1,212 owner complaints naming this part, brake master cylinder is named in 28% of them, more than any other part.
Owners name the brake master cylinder most often in the same complaint, which is not proof that one caused the other. Ask the shop whether it checked the brake master cylinder too, so you are not quoted twice for one visit.
How fast were owners driving when it happened?
25-44 mph leads at 32%.
Owners reported it most often at town speeds. Tell the shop what speed it happens at, because that narrows the diagnosis.
How serious did it get for owners?
Among the 1,212 owner complaints naming this part, being towed is the outcome owners report most often.
What it shows: Towed is the largest at 97, followed by Crash reported at 40; the smallest shown is Fire reported at 12.
Which model years show up most in the complaints?
Among the 1,212 owner complaints naming this part that state a model year, complaints cluster in a few model years instead of spreading evenly.
What it shows: 2015 is the largest at 308 (25%), followed by 2016 at 307 (25%); the smallest shown is 2025 at 14 (1%).
When in the year do owners report it?
NHTSA owner complaints about this part run furthest above the usual seasonal share in June: about 45% more of them name an incident that month than complaints about any part would predict. A complaint is a report, not a measured failure.
What it shows: June is the largest at 13% (all: 9%), followed by January at 6% (all: 9%); the smallest shown is October at 5% (all: 8%).
Do brake fluid flush problems track elevation range from lowest to highest point across states?
Across U.S. states, NHTSA owner complaints about brake fluid flush run higher where elevation range from lowest to highest point is higher, after adjusting for the makes sold in each state. This is an association across states, not proof that elevation range from lowest to highest point causes this repair.
How to read it: Each dot is a state. Further right means more elevation range from lowest to highest point (meters); higher up means more complaints for this repair than expected (1.0 is average). If the dots climb to the right, reports of this repair rise with elevation range from lowest to highest point (meters).
What it shows: States with more elevation range from lowest to highest point (meters) tend to sit higher on the chart across 33 states: a pattern in the data, not proof of cause.
- The 10 states with the most elevation range from lowest to highest point (California, Washington, Nevada, Arizona, Idaho, Utah, Oregon, Colorado, New Mexico, Texas): reports of this repair run 21% above what the makes sold there would predict, and 10 of 10 are above expected. The 10 with the least (Florida, Louisiana, Indiana, Illinois, Ohio, Wisconsin, Michigan, Missouri, Minnesota, New Jersey): 3% below, and 5 of 10 are above expected.
- Exceptions: Minnesota (27% above expected) is among the lowest but above expected.
- Split the states into thirds: the third with the least elevation range from lowest to highest point runs 1% below what the makes sold there would predict, the middle third 0% above, and the third with the most 18% above. Most of the elevation range from lowest to highest point effect sits in the third with the most.
- For elevation range from lowest to highest point, after allowing for the 1562 comparisons we ran, luck alone would produce a pattern this strong about 1 time in 16. Take out any single state and the elevation range from lowest to highest point pattern still holds.
- Weak spot: compare only states with similar average relative humidity and the pattern keeps about 24% of its strength, so part of it may come from average relative humidity instead of elevation range from lowest to highest point.
- For elevation range from lowest to highest point, of the 5 exception states, 1 read the same way for the other parts of the system (so that is the system there, not this repair) and 4 are specific to this repair.
Long mountain grades mean sustained braking, heavy loads on the transmission and driveline, and hotter engines on the climb.
Do brake fluid flush problems track brake violations per 100 truck roadside inspections across states?
Across U.S. states, NHTSA owner complaints about brake fluid flush run higher where brake violations per 100 truck roadside inspections is higher, after adjusting for the makes sold in each state. This is an association across states, not proof that brake violations per 100 truck roadside inspections causes this repair.
How to read it: Each dot is a state. Further right means more brake violations per 100 truck roadside inspections; higher up means more complaints for this repair than expected (1.0 is average). If the dots climb to the right, reports of this repair rise with brake violations per 100 truck roadside inspections.

- The 10 states with the most brake violations per 100 truck roadside inspections (Utah, Minnesota, Virginia, Texas, Idaho, South Carolina, Wisconsin, Arizona, Missouri, Colorado): reports of this repair run 23% above what the makes sold there would predict, and 10 of 10 are above expected. The 10 with the least (North Carolina, New Mexico, Nevada, Maryland, Florida, New Jersey, Kansas, Tennessee, California, Illinois): 6% above, and 7 of 10 are above expected.
- Exceptions: New Mexico (55% above expected) and Nevada (21% above expected) are among the lowest but above expected.
- Split the states into thirds: the third with the least brake violations per 100 truck roadside inspections runs 5% above what the makes sold there would predict, the middle third 12% below, and the third with the most 24% above. Most of the brake violations per 100 truck roadside inspections effect sits in the third with the most.
- For brake violations per 100 truck roadside inspections, after allowing for the 1562 comparisons we ran, luck alone would produce a pattern this strong about 1 time in 11. Take out any single state and the brake violations per 100 truck roadside inspections pattern still holds.
- For brake violations per 100 truck roadside inspections, of the 3 exception states, 1 read the same way for the other parts of the system (so that is the system there, not this repair) and 2 are specific to this repair.
Roadside inspectors count brake violations on commercial trucks, a measured violation rate for brakes under heavy use.
How many lives have brake improvements saved?
NHTSA estimates dual master cylinders and front disc brakes (FMVSS 105 and 135) saved 217 car occupants and 201 light-truck occupants in 2012 alone, and 15,560 occupants from 1960 to 2012.
| Technology | Car occupants saved in 2012 | Light truck occupants saved in 2012 | Car occupants saved 1960 to 2012 | Light truck occupants saved 1960 to 2012 |
|---|---|---|---|---|
| dual master cylinders and front disc brakes (FMVSS 105 and 135) | 217 | 201 | 10,559 | 5,001 |
| electronic stability control (FMVSS 126), the system brake work keeps working | 500 | 824 | 2,420 | 3,604 |
If this part was recalled, is the repair free?
Federal law (49 U.S.C. 30120) requires a maker to fix a recalled defect without charge for cars first bought within 15 calendar years (tires within 5), and NHTSA lists 3 recall campaigns for parts matched to a brake fluid flush since model year 2015, covering about 71,869 vehicles.
| Rule or count | What it says |
|---|---|
| Age limits | The free-remedy duty does not apply to a car first bought more than 15 calendar years, or a tire first bought more than 5 calendar years, before the recall notice. |
| Failure to fix | A repair not done adequately within 60 days of presentation is prima facie evidence of failure to repair within a reasonable time; the maker must then replace the vehicle or refund the purchase price less depreciation. |
| Free remedy | A maker must fix a recall defect without charge. |
| NHTSA recalls matched to a brake fluid flush since model year 2015 | 3 recall campaigns covering about 71,869 vehicles |
Is it recalled or covered?
| Recall number | Vehicles | Cars recalled | What the recall says |

What do owners say?
4 complaints quoted word for word, each with its NHTSA number.
They reprogrammed the brakes, put on new brake pads, milled the router and replaced the brake fluid, informing us this was needed, charging us $1210.
Upon driving another 3-4 miles the brake pedal went to floor again and low brake fluid light came on dash.
Honda World changed brake fluid and recalibrated the brakes on 9/24/21 per service requirements at 7823 miles.
Joseph(Rep) then said the $120 he quoted to fix brakes & out the door he will cancel and apply $129 for Brake Fluid Change.
Check your car
A brake fluid flush typically costs $120–$164 on our calculator's default setting: a full four-wheel flush with DOT 3 fluid at a $120/hr shop. Shop type, fluid grade and whether your car needs an ABS purge move that number more than the car itself.
What does the estimate cover, and what does it leave out?
The estimate prices a full flush at all four wheels: old fluid out, fresh fluid in, shop labor at the stated hourly rate. Fluid itself is a small share; most of the price is labor.
It leaves out repairs found during the job. A leaking hose, a seized bleeder screw or a bad master cylinder is priced separately, after diagnosis. A low estimate is a fair starting point, not a promise that nothing else turns up. Your car may also need a different fluid than the default, so check your owner's manual before comparing quotes, and note that state price levels shift the figure (see the state table on this page).
How much does each option change the price?
Every figure below is the calculator's range with one input changed from the default.
| Option | Estimate |
|---|---|
| Default: full flush, DOT 3, midsize, $120/hr shop | $120–$164 |
| Independent shop (~$100/hr) | $102–$142 |
| Dealership (~$175/hr) | $168–$224 |
| Economy car | $120–$161 |
| SUV or truck | $127–$173 |
| Luxury or performance car | $138–$198 |
| DOT 4 fluid | $127–$180 |
| DOT 5.1 fluid | $142–$212 |
| Brake bleed, one caliper | $48–$81 |
| Full flush plus ABS purge | $242–$285 |
Should you flush, bleed, or just top off?
A bleed removes trapped air, usually after a part is replaced or when the pedal feels spongy. A flush replaces the fluid throughout the system. Topping off only adds fluid to the reservoir and fixes nothing if the level dropped because of a leak.
Ask the shop which of the three it is quoting. A bleed of one caliper costs $48–$81 on the calculator, so a flush quoted at that price is probably not a four-wheel job.
How do you tell it is the problem, and how urgent is it?
Dark brown or black fluid in the reservoir, a soft or sinking pedal, a brake warning light and longer stopping distances all point to the fluid or to a hydraulic fault. A soft pedal is not always the fluid: air, a leak or a worn hose can feel the same.
Treat a sinking pedal or a warning light as same-day. Dark fluid with a firm pedal can wait for a scheduled visit. If the pedal goes to the floor, stop driving and have the car towed.
How do you get a fair quote?
Use the calculator for your car, then ask each shop four things:
- Is it a full flush at all four wheels?
- Which DOT fluid will you use, and does my car call for it?
- Does my car need an ABS purge with a scan tool?
- Did you inspect the lines, hoses and bleeders, and does the price change if you find a leak?
If the car is already in for pads or rotors, ask whether the flush is bundled; the wheels are off and the system is open anyway.
Frequently asked questions
Is a brake fluid change the same as a flush?
Many shops use the words interchangeably. A full flush replaces fluid at every wheel; a partial change leaves some old fluid in the lines. Ask which one you are getting.
Why is the dealer quote higher?
The dealership rate is about $175/hr against about $100/hr at an independent shop, which moves the same job from $102–$142 to $168–$224.
