How Much Does Brake Booster Replacement Cost?
Here’s a breakdown of the costs associated with replacing brake boosters:
A. Range
Plan to spend anywhere between $200 to $1250 for a brake booster replacement.
This includes:
- Replacement part cost: $100 to $900
- Estimated labor cost: $100 to $200
B. Factors Affecting Cost
The cost of replacing a brake booster depends on your vehicle’s make and model and local labor rates.
Other factors that affect brake booster replacement charges are:
- The complexity of access: Brake boosters are mounted to the engine compartment’s firewall between the brake pedal and master cylinder. Disassembling obstructing parts like the steering column may be necessary, which can increase costs.
- Type of brake booster: A vacuum brake booster will generally be cheaper than a hydraulic brake booster due to its simpler construction and fewer components.
Note: A vacuum brake booster uses engine vacuum to amplify brake pedal force, while a hydraulic brake booster uses power steering pressure and hydraulic fluid. - Damage to other components: Brake booster issues can come from a faulty valve or booster vacuum hose that needs replacing. If left unresolved, a bad brake booster can lead to increased braking effort, which can wear out the brake pads or tires, bumping up repair costs and work.
Is It Worth Replacing the Brake Booster?
Yes!
A faulty brake booster weakens your car’s braking power, requiring immense pressure on the brake pedals to stop or even slow down. This isn’t just inconvenient — it’s unsafe, especially in emergencies.
Moreover, any brake booster that isn’t working properly can affect other parts, including the brake pads, push rod, pedal, rotors, and tires. A vacuum brake booster failure, especially in older cars, can also reduce vacuum pressure in the engine and affect fuel inefficiency.
Signs You Need a Brake Booster Replacement
Here are some common indications:
- Longer braking distance
- The brake pedal is harder to press
- The brake pedal sits higher than usual
- Brake fluid leakage
- Lit check engine, ABS, brake warning, or sometimes traction control light
- Power steering fluid leak (for cars that use hydraulic brake boosters)
In addition, cars with a faulty vacuum booster may also experience:
- Hissing sound upon braking (indicating a vacuum leak)
- Engine malfunctions or stalls
- Poor fuel mileage
How Long Does a Brake Booster Last?
Typically, a vacuum brake booster can last from 150,000 miles to the vehicle’s entire lifespan.
A hydraulic booster can last longer as they’re usually more reliable than vacuum brake boosters.
However, several factors can shorten your brake booster’s lifespan, like:
- Excessive use of the braking system.
- Dry climates can dry rot a vacuum booster, deteriorating the internal diaphragm (flexible material that helps create vacuum pressure).
- Leaking brake fluid from a faulty master cylinder can corrode the booster’s seals.
How to Extend the Life of Your Brake Booster
Try these tips to prolong your booster’s lifespan:
- Use gradual braking to avoid straining the brake system.
- Inspect the vacuum hose regularly for any cracks or leaks.
- Check your brake fluid levels and replace it if it gets dirty.
- Look for damage or wear on your brake system parts, such as the brake booster or master cylinder, and address it promptly.
- Schedule a routine brake inspection to catch a brake booster issue early.
Can You Replace the Brake Booster Yourself?
Brake booster replacement is best left to a qualified mechanic, as the process involves complex steps like disconnecting the master cylinder and bleeding the brakes. Improper installation can lead to inconsistent braking, increased wear on brake components, and even complete brake failure.
