Call for a QuoteBrake Booster Replacement at Clutchland
The brake booster uses engine vacuum or a hydraulic pump to multiply the force you apply to the brake pedal, making it possible to stop a heavy vehicle with reasonable pedal effort. When the brake booster fails, the pedal becomes extremely hard and requires much more force to achieve the same stopping power. This is a serious safety issue, particularly in emergency situations on Spokane's busy roads and during winter driving.
Vacuum-style brake boosters use a large diaphragm that amplifies pedal force using engine vacuum. Over time, the diaphragm can tear or the check valve can fail, causing a loss of power assist. You may also hear a hissing sound from behind the dashboard when pressing the pedal. Hydraulic boosters, found on some diesel and hybrid vehicles, can develop pump or accumulator failures. In Spokane's cold winters, deteriorated seals and rubber components can fail more suddenly.
At Clutch Auto Repair in North Spokane, we diagnose brake booster issues accurately using vacuum tests and pedal force measurements. We replace failed boosters with quality units and always check the master cylinder and vacuum supply system for related problems. Call (509) 487-0161 for a quote on brake booster replacement.
