BRAKE PEDAL FREE-PLAY



See Figure 1

Free-play is the distance the pedal travels from the stop (brake light switch) until the pushrod actuates the master cylinder.

To check free-play, first measure the distance (with the carpet removed) from the floor to the brake pedal. Then disconnect the return spring and again measure the distance from the floor to the brake pedal. The difference between the two measurements is the pedal free-play. The specified free-play is 0.04-0.2 in (1.0-5.0mm). Free-play adjustment is made by loosening the locknut on the brake light switch and rotating the switch body until the specified clearance is obtained.

WARNING
If there is no free-play, the master cylinder pistons will not return to their stops. This can block the compensating ports, which will prevent the brake pads and linings from returning fully when the pedal is released. This will result in rapid brake burn-up. Free-play provides a safety factor against normal rubber swell and expansion or deflection of body parts and pedal linkage.
