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 operation procedure differs depending on the type of mechanism.
A type: Nissin mechanism
Type: Akebono mechanism (for 14" and 15" wheel rims)
C type: Akebono mechanism (for 13" wheel rims)
Note:
- A Nissin movement and an Akebono movement can be identified by the Nissin mark on the body of the Nissin movement.
- Front brake disc OD for 14" and 15" wheel rims: 262 mm
- Front brake disc OD for 13" wheel rim: 240 mm
Type A and type B:
Note: See below for operating procedure for type C.
Warning
- Never use an air hose or dry brush to clean brake components.
- Use a vacuum cleaner to prevent brake dust from entering your respiratory tract.
Attention:
- Never let brake fluid get on your car, it can damage the paint; if it gets on the paint, wash it off immediately with water.
- To prevent liquid spillage, cover 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 mechanism inlet to pull the piston out. Place a rag or wood block as shown to cushion the plunger as it is pushed out. Apply low air pressure in short bursts.
Warning. Do not put your fingers in front of the piston. Do not use high pressure
5. Remove the piston from the mechanism and check the piston for scratches.
6. Remove the boot clamp {only for type B), piston boot and piston seal.
Attention. Be careful not to damage the cylinder running surface.
Type C:
Warning
- Never use an air hose or dry brush to clean brake components.
- Use a vacuum cleaner to prevent brake dust from entering your respiratory tract.
Attention:
- Never let brake fluid get on your car, it can damage the paint; if it gets on the paint, wash it off immediately with water.
- To prevent liquid from entering, 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 sleeve A on the mechanism bracket.
4. Remove the axle boot, bushing B and bushing boot from the mechanism housing.
5. If necessary, pump air into the fluid hole of the mechanism to push the piston out. Place a rag or a block of wood as indicated to cushion the impact of the piston after it is pushed out. Apply low pressure in short bursts.
Warning. Do not put your fingers under the piston. Do not use high pressure.
6. Remove the piston from the mechanism and check whether the piston is scratched.
7. Remove the retaining ring, piston boot and piston seal.
Caution: Be careful not to damage work surfaces.
