Title: Wagon pulling to right when braking....
Post by: Brian on October 18, 2013, 09:26:53 PM

I've been trying to figure out why my right side front disc brake is
applying faster then the left...or maybe it's the other way around?   I
have done a 73 C-body disc brake swap.  Running a power brake set-up
with an aluminum master cylinder from a mid 80's dodge truck/van.  Front
 brake lines T'd straight off the rear port.  And the back brakes are on
 a SSBC manual proportioning valve.

The rotors are new off shore units...drilled and slotted.  I installed
them last year and this problem seemed to show up then.  I don't recall
the brakes doing this with the stock rotors and pads.  That is the only
thing I changed...new rotors, and some semi-metallic pads that came with
 the rotors.


I have pulled the calipers and front brake
hoses.  Replaced the front brake hoses with new Dorman hoses....no
change.  Pulled the calipers and cleaned all mounting surfaces and put
never seize in these areas.  Also new pins and lubed the rubber bushings
 so they slide like butter.  Still no change.  You can physically feel
the difference in drag when the car is in the air, with teh front wheels
 off.  You can spin the rotor much easier on the LH side, compared to
the RH side.  The left side feels "right" with just a small amount of
drag....the right side is too much in my opinion.  With the calipers
removed the rotors both spin freely to about the same degree.  It's once you re-install the brake pads, and then bleed the brakes that the drag starts. 

Thoughts...opinions?

Look into the left brake

Good idea Steve.  If the left is not functioning properly the right one will yank it.
