10. Inspect the bore of the master cylinder.
• If the bore is undamaged, clean it thoroughly
and continue with assembly.
• If the bore is slightly worn or scored, it may be
honed using a BRM® flex-hone according to the
manufacturers instructions.
11. Clean all parts that are to be assembled.
11a. Initial cleaning may be done with Stod-
dard solvent.
11b. Final cleaning should be done using hot
soapy water (dish washing detergent is
suitable), a nylon brush and a nylon bore-
bush.
11c. Rinse and dry all parts thoroughly.
12. Assemble the pistons using the new parts con-
tained in the kit, installed as described in the dis-
assembly process.
NOTE: Use a small amount of thread locking
compound such as Loctite® 242 (blue) on the
shouldered screw that fastens the transfer
spring, cup, and spring seat to the rear piston.
13. Lubricate the bore of the master cylinder with
brake fluid. Lubricate the pistons with brake fluid
or a suitable brake assembly lubricant such as
Sil-Glyde®, available from NAPA® auto parts
(p/n:765-1351).
CAUTION: Do not get brake fluid on painted sur-
faces. Brake fluid dissolves or damages many
types of paint.
14. Carefully insert the front piston, spring end first,
into the bore of the cylinder.
15. Fixture the master cylinder into a vise as was
done for disassembly.
16. Carefully insert the rear piston, spring end first,
into the bore of the cylinder.
