| Title: BRAKE SYSTEM (OTHER): BRAKE PEDAL: ADJUSTMENT (2008 Sequoia) | ||
ADJUSTMENT
1. CHECK BRAKE PEDAL HEIGHT
|
(a) Check the brake pedal height. Standard pedal height from dash panel: 179.9 to 189.9 mm (7.08 to 7.48 in.) NOTICE:
Do not adjust the pedal height. Doing so by changing the push rod length will structurally change the pedal ratio. If the pedal height is incorrect, check that there is no damage in the brake pedal, brake pedal lever, brake pedal bracket and dash panel. Even if there is damage, there is no problem if the reserve distance is within the standard value. If necessary, replace these parts. |
2. CHECK AND ADJUST STOP LIGHT SWITCH ASSEMBLY
HINT:
If the pedal height is incorrect, check and adjust the stop light switch clearance.
(a) Disconnect the stop light switch connector.
(b) Turn the stop light switch counterclockwise and remove it.
|
(c) Insert the stop light switch until the body hits the cushion. NOTICE:
When inserting the stop light switch, support the pedal from behind so that the pedal is not pushed in. |
(d) Make a quarter turn clockwise to install the stop light switch.
NOTICE:
The turning torque for installing the stop light switch should be 1.5 N*m (15 kgf*cm, 13 in.*lbf) or less.
HINT:
Due to the inverse screw structure, if the stop light switch is turned clockwise, the stop light switch moves in the direction to be pulled out.
(e) Connect the stop light switch connector.
(f) Check the protrusion of the rod.
Standard protrusion of the rod:
0.5 to 2.6 mm (0.020 to 0.102 in.)
3. CHECK PEDAL FREE PLAY
|
(a) Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster. |
(b) Push in the brake pedal until the beginning of the resistance is felt. Measure the distance as shown in the illustration.
Standard pedal free play:
1.0 to 6.0 mm (0.0394 to 0.236 in.)
4. CHECK PEDAL RESERVE DISTANCE
(a) Release the parking brake pedal.
|
(b) With the engine running, depress the brake pedal and measure the pedal reserve distance as shown in the illustration. Standard pedal reserve distance from asphalt sheet at 490 N (50 kgf, 110.2 lbf): More than 104 mm (4.09 in.) If incorrect, troubleshoot the brake system
