WARNING: Do not re-use fasteners that are worn or deformed in normal use.
Some fasteners are designed to be used only once, and are unreliable and may fall if used a second time. This includes, but is not limited to, nuts, bolts, washers, circlips and cotter pins. Always follow recommendations in this manual-replace these fasteners with new parts where indicated, and any other time it is deemed necessary by inspection.
To siphon brake fluid, always use a bleeder bottle which is only used to siphon brake fluid.
Brake fluid is poisonous and must NEVER be removed by siphoning with your mouth.
Note: Install complete repair kit
After installing the brake pads, depress the brake pedal firmly several times before moving the vehicle to properly seat the brake pads in their normal operating position.
The brakes can be tested on a commercial brake dynamometer provided the speed of the two dynamometer drive rollers is not more than 5.5 km/h (3.3 mph).
Tightening torque for the brake lines is 15 Nm (77 ft lb)
1. Brake hose
Do not disconnect the brake hose from the caliper when replacing brake pads.
CAUTION: Do not allow the caliper to hang by the brake hose. The unsupported weight can stretch and damage the hose.
2. Caps
Remove for access to guide pin
3. Guide pin 25 Nm (18 ft lb)
4. Brake line 15 Nm (11 ft lb)
Install into caliper housing
When tightening to brake hose, counter hold on brake hose hex
Make sure lugs are properly seated in retainer grooves
5. Brake caliper housing
Unbolt from brake carrier for replacing brake pads
Servicing brake caliper, refer to Brake Caliper/Service and Repair Service and Repair
6. Ribbed bolt 125 Nm (92 ft lb)
Clean ribbing if re-using
7. Brake carrier
Bolt to wheel bearing housing
8. Brake pads
CAUTION: The inner brake pad (with expanding spring) is marked with an arrow that must point in the direction of rotor rotation when the vehicle is moving forward. Incorrect installation can result in excessive noise.
Outer pads have an adhesive with a protective sheet on the backing plate; remove this sheet before installing
Different versions are available, check with your parts department for the correct application
Always replace as a set on both wheels of an axle
Removing and installing, refer to Brake Pad/Service and Repair Service and Repair
Brake pad wear limit (friction material): 2 mm (0.08 in)
Brake pad wear limit (including backing plate): 7 mm (0.28 in)
Note: Before installing new brake pads, thoroughly clean the brake calipers (free of grease). Pay particular attention to removing any adhesive residue from the outer brake pad contact surfaces.
9. Retaining spring
Insert into both holes in brake caliper housing
Once spring ends are seated in holes, press retaining spring under brake carrier
CAUTION: If the spring is not installed correctly, the outer brake pad alignment mechanism will not be able to compensate for wear, and increased pedal travel will result.
10. Brake disc
Always replace as a set on both wheels of an axle
To remove, first unbolt caliper
Resurface evenly on both sides starting from thickness when new
