8. Remove the rear disc brake piston seal ring.

a. Using a screwdriver wrapped with protective tape, 

carefully pry out the rear disc brake piston seal ring 
(arrow) from brake cylinder rear ring groove.

Inspection

1. Check brake cylinder and the piston.

a. Check piston and bore for scratches or corrosion. If there are scratches or corrosion, remove them with 

fine sand cloth.

b. Remove dirt on piston with a soft brass wire brush and coarse cloth. Do not clean the piston with 

polishing cloth or sand cloth, as this may damage its surface. If surface of piston is damaged, replace it. 
If piston is stuck or bore is worn or corroded, replace entire brake caliper assembly. Using polishing 
cloth to remove small corrosion points inside the bore.

2. Check brake caliper fixing bracket and brake caliper guide pin set.

a. Clean the contact surface of brake caliper fixing bracket and brake lining support gasket with brake 

cleaner. Check for deformation, cracks, rust and foreign matter which is difficult to remove.

b. Check brake caliper guide pin rubber dust boot for deformation, cracks, worn and foreign matter which 

is difficult to remove.

c. Install brake caliper guide pin and brake caliper guide pin rubber dust boot to brake caliper fixing 

bracket. The brake caliper guide pin set should move smoothly without being stuck when pushing it with 
hand; otherwise replace it.

d. After installing the brake lining, check if it is easy to fall out (due to insufficient elasticity of support 

gasket). Replace as necessary.

3. Check brake lining.

a. Visually check brake lining for flatness, and also check for excessive wear. If condition of lining cannot 

be confirmed accurately only by visual inspection, a physical check will be used as necessary.

b. Measure the minimum brake lining thickness. When 

the minimum thickness of brake lining is 2 mm or less, 
replace the brake lining.

c. When replacing excessively worn brake linings (inner and outer), it is also necessary to replace linings 

on the opposite side of vehicle as well as unchecked linings to maintain proper braking performance. If 
it is unnecessary to replace brake linings, be sure to reinstall brake linings to the original positions.

4. Check brake disc.

a. Minor scratch or wear on brake disc surface is acceptable. If severe scratch or deformation exists, the 

brake disc must be replaced.

b. Excessive wear of brake disc may cause poor contact between brake lining and surface of brake disc. If 

protrusion on the disc is not removed before installing new brake lining, abnormal wear of brake disc 
will be caused.

c. It is normal that the surface of brake disc is worn when replacing brake lining. If cracks or burned spots 

exist, the brake disc must be replaced.

5. Check brake disc thickness.

a. Using a vernier caliper, measure the brake disc 

thickness at the center of brake lining contact surface 
as shown in the illustration.
Standard thickness: 10 mm
Minimum thickness: 8 mm

b. If it is less than the minimum thickness due to wear of brake disc, replace brake disc.

Assembly

HINT:

 Use the same procedures for the right side and left side.

 Procedures listed below are for the left side.

1. Install the rear disc brake piston seal ring.

a. Apply a light coat of grease to entire inner and outer 

circumferences of new rear disc brake piston seal 
ring.

b. Install the rear disc brake piston seal ring onto the 

brake cylinder.

RT21260660

CAUTION

 DO NOT machine brake disc, because it may make the brake disc thickness less than the minimum 

thickness.

CAUTION

 When assembling brake caliper assembly, always keep your hands clean. 
 When assembling brake caliper assembly, always use clean new brake fluid.
 Never use old seal ring for front disc brake piston.
