INSPECT AND ADJUST BRAKE PEDAL HEIGHT
Check the brake pedal height.
Turn back the carpet.
Turn back the dash panel insulator assembly from the slit provided on the dash panel insulator assembly.
Measure the shortest distance between the brake pedal pad surface and floor panel.
| *1 | Stop Light Switch Assembly |
| *2 | Floor Panel |
| *a | Brake Pedal Height |
| Pedal height from floor panel |
|---|
| 138.5 to 148.5 mm (5.46 to 5.84 in.) |
If pedal height is incorrect, inspect and adjust the push rod length according to the procedure below.
Adjust the push rod length.
Remove the stop light switch assembly Click here.
Remove the brake booster with master cylinder assembly Click here.
Loosen the lock nut and adjust the push rod length shown in the illustration by turning the brake master cylinder push rod clevis to achieve the correct length.
| *1 | Lock Nut |
| *2 | Brake Master Cylinder Push Rod Clevis |
| *a | Push Rod Length |
| Push rod length |
|---|
| 115.5 to 116.5 mm (4.55 to 4.58 in.) |
Tighten the lock nut.
Install the brake booster with master cylinder assembly Click here.
If the pedal height is incorrect even when the push rod length is adjusted, check the brake pedal support assembly and floor panel.
If necessary, replace the brake pedal support assembly.
Install the stop light switch assembly Click here.
After adjusting the pedal height, check the brake pedal free play.
INSPECT AND ADJUST BRAKE PEDAL STROKE SENSOR ASSEMBLY
Loosen the 2 bolts.
Connect the Techstream to the DLC3.
Turn the power switch on (IG).
Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/TRAC / Data List "Stroke Sensor".
Read the stroke sensor value in the Data List, and turn the brake pedal stroke sensor assembly slowly to the right or left to adjust the output voltage so that it is within the following range.
| Standard voltage (without the brake pedal depressed) |
|---|
| 0.8 to 1.2 V |
Tighten the 2 bolts.
Note
Do not depress the brake pedal after turning the power switch on (IG).
Turn the Techstream off and turn the power switch off.
Disconnect the Techstream.
INSPECT BRAKE PEDAL FREE PLAY
Depress the pedal until a slight resistance is felt. Measure the brake pedal free play as shown in the illustration.
| *a | Brake Pedal Free Play |
| Pedal free play |
|---|
| 1.0 to 6.0 mm (0.0394 to 0.236 in.) |
If the pedal free play is not as specified, check the stop light switch clearance Click here. If the pedal free play is as specified, proceed to the Inspect Brake Pedal Reserve Distance procedure.
INSPECT BRAKE PEDAL RESERVE DISTANCE
Tech Tips
Measure the distance at the same point used for the brake pedal height inspection.
Release the parking brake.
With the power switch on (READY), depress the brake pedal and measure the pedal reserve distance.
| Pedal reserve distance from the floor panel at 500 N (51 kgf, 112 lbf) |
|---|
| More than 92 mm (3.62 in.) |
If the distance is not as specified, troubleshoot the brake system Click here.
