I have a Firebird that when I hit the brakes it pulls to the right real hard and when you let off it pulls real quick to the left then it is ok. (These are power brakes also) I changed both front brake calipars and had all front end joints checked when I had a front end elignment done. Rear tracking bar broke and replaced it...made it a bit better after that but still pulls, any idea's?

Here as some possibilities....small amount of air in your brake hydraulic lines, steering gear lash too excessive (do you have any slop in your steering wheel), malfunctioning rear brakes although I don't think that would be the primary cause of what you are seeing. Different tire sizes on the front....others may have more ideas...good luck Scott

Have you changed both front brake hoses? if not change ,the hose will come apart inside and will check valve and hold the cal.on or not let fluid flow in.

[dmorris1200]

Yes hoses would be the first thing I would change. If that doesn't fix it try swapping front rotors right to left, left to right. It may sound stupid but I've seen rotors cause a pull.

Are these calipers cast iron or aluminium? I struck a similar problem, and after working through all of the steps, many of which are listed here such as checking for air in lines, swapping / replacing pads, rotors, I eventually found a hair line crack in the alloy caliper near the slide pin mount.When the brake was applied, the caliper body would flex rather than applying the full pressure to the pads, resulting in uneven braking.

I would suspect the hoses like the other guys, hoseslose there texture what happens is the hose sucks together when it releases.(wrenchturner)

[blown69stang]

Hoses- Cheap factory hoses lose their tensile strength integrity and tend to collapse or expand and don't transfer all the braking pressure directly to the calipers. Check them/replace them but do something with those first. You could have a clog in one hose or hose connection which prevents the pressure from changing quickly and efficiently. Have you checked out the brake fluid for being dirty?

I had the identical problem in a '72 Ford Ranchero with an Equ-lol rear end and coil rear suspension. The car was dangerous to drive especially on the freeway where under acceleration pulled hard to the right when you let off the gas it dove to the left. I fixed it when I replaced all of the rear end suspension rubber grommets. On Fords they are pressed in. If I had to do it again I would use Polyurathane replacement parts. NAPA does not carry but check with Performancesuspension.com Good luck, this was tough to find on my car!!! r
