How To Read Your Brakes
Rate of Wear on Lining Differs
|
Possible Causes
|
![]() By
law, all vehicles manufactured after June
1980 must have operable brakes on all axles
of all units originally equipped with
brakes. If each wheel has the same
mechanical input, the same linings at proper
frictions levels, and the air system is ok,
there should be no noticable differences in
rate. |
|
Solution
|
![]() Use
a ruler to measure the push rod accurately.
Measurement should be the same - applied and
released. There should be no excessive play
- the push rod must begin turning the cam
head immediately. Both brakes across the
axle and all brakes on a tandern set must
have the same adjustment. The result of
every brake receiving the same mechanical
input is even wear and predictable
performance. In other words, a balanced
braking system. |
