caliper. Two retaining pins must be removed on
heavy duty Corvette front calipers. Identify the
inboard and outboard shoe if they are to be reused.
5. Remove the end of brake hose at bracket by re-
moving U-shaped retainer from the hose fitting and
withdrawing the hose from bracket.
6. Remove the caliper assembly from the mounting
bracket by removing two hex head bolts.
Disassembly (Fig. 39)
1. Clean exterior of caliper with Declene, or equivalent.
On Chevrolet and Corvette front caliper, remove
brake hose.
2. Separate the caliper halves by removing the two
large hex head bolts. Remove the two small "O"
rings from the cavities around the fluid transfer
holes in the two ends of the caliper halves.
3. To free the piston boots so that the pistons may be
removed, push the piston down into the caliper
as far as it will go. Insert a screwdriver blade
under the inner edge of the steel ring in the boot,
and using the piston as a fulcrum, pry the boot from
its seat in the caliper half.
CAUTION: Use care not to puncture seal when
removing pistons from caliper.

4. Remove the pistons and piston springs from the
caliper half. Remove the boot and seal from their
grooves in the piston.
Cleaning and Inspection
1. Clean all metal parts using Declene, or equivalent.
Remove all traces of dirt and grease. Do not use
mineral base solvents to clean brake parts.
2. Using an air hose, blow out all fluid passages in the
caliper halves, making sure that there is no dirt
or foreign material blocking any of these passages.
3. Discard all rubber parts. Boots, seals, and "O"
rings should be replaced with new service kit parts.
4. Carefully inspect the piston bores in the caliper
halves. They must be free of scores and pits. A
scored or otherwise damaged bore will cause leaks
and unsatisfactory brake operation. Replace the
caliper half if either bore is damaged to the extent
that polishing with very fine crocus cloth will not
restore it.
