Rear Disc Brake Rotor/Disc And Caliper Service:

REMOVAL
1. Drain the brake fluid.
2. Follow the procedure in the above image.

CHECKING BRAKE DRAG





1. Measure hub torque to obtain value (A) with pads removed to measure brake drag torque. Torque value will be used later to calculate brake drag force with the pads installed.

NOTE: Tighten the nuts in order to secure the disc to the hub.

2. Securely attach the pad clip to the caliper support.





3. Clean piston and insert into cylinder (caliper) with special tool.
4. Be careful that the piston boot does not catch and tear as the caliper assembly and lock pin are installed.
5. Check brake drag torque as follows.

a. Start engine and hold brake pedal down with a pressure of 196 N (44 lbs.) for 5 seconds.
b. Stop engine.
c. Turn brake disc forward 10 times.





d. Check hub torque to obtain value (B) with spring scale.
e. Calculate the drag torque of the disc brake by equating the difference between hub torque (B) and hub torque (A).
6. If the difference between brake drag torque and hub torque exceeds 4 Nm (35 inch lbs.) or less at 69 N (15.4 lbs.), disassemble piston and clean the piston. Check for corrosion or worn piston seal, and check the sliding condition of the lock pin and guide pin.

INSTALLATION
1. Follow the removal procedure in reverse order.
2. Fill master cylinder with brake fluid.
3. Bleed the brake system. Service and Repair
