[s-cars] Brake Fluid Equalizer

[Peter Golledge]

Max,

Ummm if the rears are only hitting the external face of the rotors the
caliper sliders are binding and/or shot.  This needs to be fixed in addition
to the proportioning valve.  As for the other mechanic not checking the rear
brakes.... See "monkey lads" in any number of threads on Audifans.

Hi all,

Just had the original brake fluid equalizer/proportioner [C$355] changed.
Found in front of the left rear wheel.
Anyone know what the equalizer has inside? Mechanic says equalizer was
seized, practically only the front brakes were working. Anyone can give some
knowledge of the function of the equalizer? The car with the old equalizer
was making boing-boing spring noises at the back, most noticeable in an
underground garage. With the new equalizer very smooth, quiet boingless
braking.
The rotors in the back were rough, rusty on the inner surfaces. only the
outer surfaces were touched by disc pads. 

Should the mechanic 3 weeks earlier who changed the front brake shoes C$135
and both front rotors, each C$140 have noticed that the equalizer was
defective? The car was making rubbling noises when the brakes were applied
after this service, with time I was aware that this noise was coming from
the back, which prompted me to see my other mechanic.

There has never been discussion of the brake fluid equalizer as far as I
know in this group.
It seems to me it might be a good idea to grease the shoulder joint of an
equalizer to prolong its life.
