Disassembly
There are 6 types of front brake mechanism, which can be classified into 3 groups (type A, type B and type C). Check the type of brake mechanism before starting work because the operating procedure differs depending on the type of mechanism.
A type: Nissin mechanism
B type: Akebono mechanism (for 14" and 15" wheel rims)
With type: Akebono mechanism (for 13" wheel rims)
Note:
- Nissin movement and Akebono movement can be identified by the Nissin mark applied to the Nissin movement case.
- Front brake disc OD for 14" and 15" wheel rims: 262 mm
- Front brake disc OD for 13" wheel disc: 240 mm
Type A and Type B:
Note: For type C, see below for operating procedure.
Warning
- Never use an air hose or dry brush to clean brake components.
- Use a vacuum cleaner to avoid inhaling brake dust.
Attention:
- Never allow brake fluid to come into contact with your car, it may damage the paint, if it does come into contact with the paint, wash it off immediately with water.
- To prevent fluid spills, cover the hose connections with a rag or paper towel.
- Wash all parts with brake fluid and let dry, blow out all channels with compressed air.
1. Remove the union bolt and disconnect the brake hose from the mechanism.
2. Remove the mechanism bolts, then remove the mechanism from the bracket.
3. Remove the mechanism axles and axle boots from the mechanism bracket.
4. If necessary, apply compressed air to the inlet of the mechanism to push the piston out. Place a rag or wooden block as shown to cushion the piston as it is pushed out. Apply low air pressure in short bursts.
Warning: Do not place your fingers in front of the plunger. Do not apply high pressure
5. Remove the piston from the mechanism and inspect the piston for scratches.
6. Remove the boot clamp (only for type B), piston dust boot and piston seal.
Caution: Be careful not to damage the working surface of the cylinder.
Type C:
Warning
- Never use an air hose or dry brush to clean brake components.
- Use a vacuum cleaner to avoid inhaling brake dust.
Attention:
- Never allow brake fluid to come into contact with your car, it may damage the paint, if it does come into contact with the paint, wash it off immediately with water.
- To prevent liquid from leaking, cover the hose connections with a rag or paper towel.
- Wash all parts with brake fluid and let dry, blow out all channels with compressed air.
1. Remove the union bolt and disconnect the brake hose from the brake mechanism.
2. Remove bolt B of the mechanism, turn the mechanism upside down, then remove the mechanism from the bracket.
3. Remove the guide axle boot from bushing A on the mechanism bracket.
4. Remove the axle boot, bushing B and bushing boot from the mechanism housing.
5. If necessary, inject air into the fluid port of the mechanism to push the piston out. Place a rag or wooden block as an indication to cushion the impact of the piston after it is pushed out. Apply low pressure in short bursts.
Warning: Do not place your fingers under the piston. Do not apply high pressure.
6. Remove the piston from the mechanism and check if the piston is scratched.
7. Remove the retaining ring, piston dust boot and piston seal.
Caution: Be careful not to damage work surfaces.
