1. Pedal stop lock ring out of
seat in master cylinder. |
1. Remove the master cylinder and
rubber boot. Examine the lock ring seat to see that the seat groove is
sufficiently deep to hold the lock ring securely. See that the lock ring
is flat and has ample tension to expand it tightly into the bottom of
the groove. Reassemble the stop and lock ring, being certain that the lock
ring is seated into the bottom of the groove. After replacing the master
cylinder, bleed the lines. |
