Disassembly and Assembly
Disassembly and Assembly of Caliper Assembly
DISASSEMBLY
1. Remove the sliding pin bolt, and then remove the pad, shim, shim cover, and pad retainer from the torque member.
CAUTION: When removing the pad retainer from the torque member, lift it in the direction indicated by the arrow in the figure so that it does not deform.
2. Remove sliding pins and sliding pin boots from torque member.
3. Place a wooden block as shown, and blow air from union bolt mounting hole to remove pistons and piston boots.
CAUTION: Do not get your fingers caught in the piston.
4. Remove the piston seal from the cylinder body using a screwdriver or suitable tool.
CAUTION: Be careful not to damage cylinder inner wall.
CALIPER INSPECTION
Cylinder Body
CAUTION:
- Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.
- Check for corrosion, wear, or damage to the cylinder inner wall, and replace the caliper if there are any non-standard conditions.
- Minor flaws caused by corrosion or a foreign material can be removed by polishing the surface with a fine sandpaper. Replace the cylinder body, if necessary.
Torque Member
Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.
Piston
CAUTION:
- Since the piston surface is plated, do not repair using sandpaper.
- Check piston surface for corrosion, wear, and damage. If any non-standard condition is detected, replace applicable part.
Sliding Pins, Sliding Pin Bolts, and Sliding Pin Boots
Check sliding pins, sliding pin bolts, and sliding pin boot for wear, damage, and cracks. If damage or deformation is present, replace the affected part.
ASSEMBLY
CAUTION: Do not use Nissan Rubber Grease (KRE00 00010 or KRE00 00010 01) when assembling.
1. Apply rubber grease to the piston seal and attach to cylinder body.
CAUTION: Do not reuse the piston seals.
2. Apply brake fluid or rubber grease to the piston boot, place it on the piston, and firmly insert the piston boot cylinder-side lip into the cylinder body groove.
CAUTION: Do not reuse the piston boot.
3. Apply brake fluid or rubber grease to the piston, insert into the cylinder body by hand and firmly attach the piston boot piston-side lip into the piston groove.
CAUTION: Press the piston evenly and vary the pressing point to prevent cylinder inner wall from being rubbed.
4. Install sliding pins and sliding pin boots to torque member.
5. Attach the inner shim and shim cover to the inner pad and the outer shim to the outer pad.
6. Install cylinder body. Tighten sliding pin bolt to the specified torque.
