How much does it costs to replace a brake booster?

The cost to replace brake booster ranges from around $300 to $1,300, with most jobs coming in at the low end of that range. The brake booster sits between the brake pedal linkage and the brake master cylinder. It uses engine vacuum or an electric motor to help you push hydraulic fluid through the master cylinder to your brakes. Due to the placement of the part, this job is usually just a matter of unbolting the old booster from the linkages and firewall, and fitting a new one in its place. On some vehicles, cowl and trim pieces may need to be removed to get full access. This keeps labor costs to within $100-$200. Most boosters cost between $150-$300, but there are some replacements that are far more expensive.
