Precautions on Installation
Reassemble front brakes in the reverse order of disassembly, using care in the following points:
CAUTION:
^ Wash each part before installation in clean fresh brake fluid or alcohol.
^ Never use other solvents or thinner
^ Before installing piston and piston seal to cylinder, apply brake fluid to them.
^ After reassembling brake line, bleed air from lines
Piston Seal
The Piston Seal is used to seal the piston and cylinder and to adjust the clearance between the pad and disc. Whenever you rebuild the caliper, always replace this seal. During installation, be sure that seal fits properly into groove and is not twisted in any way.
Piston and Boot
Install dust boot before installing the piston. Make sure to install boot in the proper direction.
To facilitate installation of the dust boot into the caliper, position the outer end of the piston so that it projects out of the end of the caliper by about 10 mm (0.4 in.). After boot is properly installed, install the boot set ring.
Caliper
Before installing the caliper to the carrier, make sure that the guide pin inserted into each caliper mounting hole moves freely in each direction.
