Pedal height refers to the distance the brake pedal sits off the floor. If the pedal height is not within the specified range, it is important to check for any damage to the brake pedal, pedal arm, pedal mounting bracket, and dash panel. In such cases, the brake light switch should be adjusted, but it is advised not to adjust the pushrod length as it can alter the pedal force ratio. It is worth noting that if the pedal reserve height is satisfactory, no changes are necessary. To measure the brake pedal height accurately, ensure that the pedal is fully returned and activate the power brake booster by starting the engine and depressing the accelerator several times. The measurement should be taken with the carpet pulled back and the brake pedal pad removed. Pedal freeplay refers to the pedal slack or the distance the pedal can be depressed before it affects the brake system. If the pedal height is not within the specified range, it is important to check for any damage to the brake pedal, pedal arm, pedal mounting bracket, and dash panel. In such cases, the brake light switch should be adjusted. However, adjusting the pushrod length is not recommended as it can alter the pedal force ratio. Similar to pedal height, if the pedal reserve height is satisfactory, no changes are necessary. To measure the brake pedal freeplay, turn off the engine and depress the brake pedal several times before taking the measurement. If the freeplay is incorrect, adjust the brake light switch. If the issue persists, troubleshoot the brake system. Pedal reserve height refers to the distance the pedal sits off the floor when fully depressed, measured from the center of the brake pedal pad to the dash panel. If the reserve height is not within the specified range, it is important to check for any damage to the brake pedal, pedal arm, pedal mounting bracket, and dash panel. If the reserve height is still incorrect, troubleshooting the brake system is necessary. To adjust the brake light switch, disconnect the electrical connector and remove the switch by rotating it counterclockwise. Reinsert the switch until the body contacts the cushion, then turn it 1/4-turn clockwise to lock it into position. The plunger on the brake light switch should be measured for proper extension, and if necessary, the brake pedal can be pulled out slightly before reinserting the switch to achieve the correct distance.
