Brake Booster Replacement Cost & Pricing
Replace the vacuum or hydraulic brake booster that multiplies the force of your foot on the pedal. A failed booster makes brakes feel rock-hard and require extreme effort to stop.
Typical Brake Booster Replacement cost
$350–$1,080, with an average estimate of $650 before vehicle-specific adjustments.
What to expect
Difficulty: moderate. Typical labor time: 2–4 hours.
Mechanic's tip
A hissing sound when pressing the brake pedal, or a pedal that suddenly requires much more force, points to a failing booster. The booster is typically replaced together with the master cylinder since they share the same mounting location and labor. Check the vacuum hose to the booster first — a cracked hose is a $10 fix that mimics booster failure.
