DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Brake Pedal: Inspection
- Move the brake pedal pads in a horizontal direction with a force of approx. 10 N (1 kgf, 2 lbf), and check that the pedal deflection is in the range of specifications.CAUTION: If excessive deflection is noted, replace with a new bushing.
Deflection of brake pedal:
Wear limit: 5.0 mm (0.197 in) or less
- Check the position of the pedal pad.
Pedal height L: 140 - 150 mm (5.51 - 5.91 in)
Brake pedal free play A: 0.2 - 0.5 mm (0.008 - 0.02 in) [When pulling the brake pedal upward with a force of less than 10 N (1 kgf, 2 lbf).]
- If it is not within the specification, loosen the lock nuts of brake booster operating rod, and rotate the rod to adjust the pedal height L within the specification.
