locking right front bad at AX, could it be shocks unevenly worn? Options

[mskala]

Subject tries to say it all. Before I get the new tires on, I wanted
to understand why everybody tells me I'm smokin' the right front
tire bad under heavy braking.

I corner weighted the thing with my equiv weight, and of course
that's the lightest part of the car, but it shouldn't be that bad.
Calipers are only a few years ago rebuilt and I don't notice any
different pad wear left to right.

The front shocks are original. Could they be acting different from
each other? I have 21mm torsion bars so the car is stiff, I
wouldn't be able to tell from bouncing the car.

Thanks all,

How are your hoses? Original Rubber? Those can blister inside trapping fluid. The pedal force will operate the caliper but the blistered line won't let the pressure off like it normally should.

Caliper again. I rebuilt mine the first time because of a sticky right. I didn't do a thorough job with the piston and the cylinder and the rebuild did the same thing. I just recently performed another rebuild (this time with new lines as well) and everything is perfect.

I had an unequal braking up front....ended up being pads...when they start to get close to end of life they get grabby.

In the past....I have also seen swollen lines, sticky pistons and just plain jane needed new fluid....

Worn suspension parts (e.g., shocks, ball joints, etc.) can also cause that.

Mark, I always locked up the right front...lightest corner by far...

That is why I moved the battery as far to the right front as possible...I havn't run it yet but it should help..

New pads, old pads, same story..my front bars are very stiff.

I just think that it is due to the weight transfer.....go with monster rear springs....herb

I get to watch my co-driver during his passes. He locks the right front often. I seldom lock em' up......which may be why he's a tad quicker....but that's another problem (IMG:style_emoticons/default/biggrin.gif) .

Another buddy( a fast one) with a 9eleben does the same thing.

As long as the car isn't pulling to the right side during
more normal (non locking) braking, I don't see a problem.
One wheel is gonna lock first as you're searching for the threshold.

If you take your hands off the wheel and hit the brakes, the car should stop straight. If not, there's a problem.
I do this test after I do any brake work.

AX brings out the worst in any car.

Does the car pull to the right when you brake in a normal situation?

Try it with your hands off the wheel, in a safe place of course.

I should've added some of this info, but I forgot. I did put in
all new rubber lines. I see most of the other cars lock right
front also, early 911's and even a 924 sunday. I know I should
be more 'judicious' in brake application, but it's hard when
the tires don't make noise and the smoke is way behind you (IMG:style_emoticons/default/biggrin.gif)
The car does brake straight normally.

Thanks all

sounds like weight transfer.
I would try new pads, they are cheap.

rotors might not be true and that would do it.

Tom T always locks, as does Chris, but not Mark...
Use the pads Mark is using, he swears by them for both street and track...cant remember the names, just email him.

Hey Rich...you don't have an extra LSD laying around do you? Are you running that locked diff?
