INSPECTION
Clean all the internal parts thoroughly with fresh
brake fluid or alcohol. Do not use mineral oil like
kerosene, petrol, diesel etc. After thoroughly
cleaning, examine all parts for damages and
corrosion.
Check the various parts for the following:
1. PISTON
Outer surface should be free from nicks, score or
rust and should feel smooth to touch. Do not use
emery paper on piston surface.
2. CALIPER HOUSING
Bores should be free from score, pitting and
corrosion. The seal grooves in the bore should be
thoroughly cleaned and no nicks should be there
at the edges. If the above conditions are
satisfactory then replacement with appropriate kit
will give satisfactory performance. If not the
caliper assembly should be replaced.
3. CARRIER
Remove the grease from sliding pin bores and
clean the bores thoroughly. The carrier-machined
surface should be free from any damages; hit
marks etc. and the sliding pin bores should be
free from ovality and damages. Check for the
carrier mounting bolts.
4. SLIDING PINS
Should be free from rust, bends and step
formation due to wear. If necessary, replace the
sliding pin with new one.
