Brake Pedal Travel Measurement & Inspection
WARNING: This page is about a different car, the 2002 Pontiac Firebird and 2002 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Brake pedal travel is not adjustable. Most low brake pedal problems are caused by air in hydraulic system and improper rear brake adjustment. Other less frequent causes of excessive pedal travel are incorrect power booster push rod length, worn linings, misadjusted parking brake, contaminated brake fluid, uneven brake pad wear, damaged pads, loose brake components, low brake fluid level, or a leak in hydraulic system. Most high brake pedal problems are usually caused by low engine vacuum, a vacuum leak, or a malfunctioning power booster. Bleed hydraulic system before performing procedure and ensure rear brake adjustment is correct. Following procedure determines if brake pedal travel is as specified.
- Install Brake Pedal Effort Gauge (J-28662) onto brake pedal. Hook end of tape measure over top of brake pedal. Measure and record distance to rim of steering wheel.
- Block wheels. Run engine at idle. Shift transmission into Neutral. Apply 100 lbs. (45 kg) of force to brake pedal. Measure and record distance to rim of steering wheel again. Difference between measured values is brake pedal travel. See BRAKE PEDAL TRAVEL SPECIFICATIONS table.
- If brake pedal travel is not within specification, ensure brake power booster piston rod length is correct and rear brakes are adjusted. Recheck brake pedal travel. If brake pedal travel still exceeds specification, repair brake system.
