Braking anomoly

[nsxhale]

I own a 1993 5 speed with 22,500 miles. The problem is an intermitent pull to the left upon brake application. It only occurs once in approximately ten applications. The pads have been inspected and are O.K. There is no chatter indicating rotor warpage. The pull is quite violent when it occurs and cant be anticipated. I thought I would submit this problem to the expertise within this forum before letting the dealership run wild with their diagnostic imaginations. Thanks guys for your great input. Mark

I had this happen on the track one weekend... turns out that my INSIDE LEFT REAR pads were worn down (at the backing plate), enough to score and damage the rotor.
Rotors are $$$, pads are cheap.

Rotors aren't that expensive, but I agree that pads are the first thing to check.

It's also possible that one of the calipers is sticking and needs lubrication. (Which can also be a cause for one pad to wear quicker than the other.)

This should be relatively routine for the dealer to track down.

I'm running aftermarket 13" rear rotors, which are (currently) pricey.

Due to the piston design of the rear slider caliper, I believe the inside pad wears MUCH faster than the outside ones.

I would also submit that this is similar to a problem I had and it was air in the antilock brake mechanism. Maybe you should have this bled at the dealer with their special bleeder tool. It was a stange thing and I was suprized the solution was so simple.

Worth a try especially if there has been and brake fluid change done, even if not recently. It took 8 months for my problem to show up after the brake fluid change.

Also, see if it's happening consistently in the same place(s) that you drive. Sometimes a rut or crown on the road will make the car pull quite violently under braking.

Manuel --

I have replacement rotors that are compatible with the RM kit, available in cross drilled and slotted.

I also have a set of Hawk RPS pads, new, complete set for the RM and ScienceofSpeed big brake kits. I'll sell to you for 50% off the price new.

I suggest anyone looking for replacement pads for their stock brakes to take a look at the Panther Plus compound from Carbotech. The pad performs far better than any of the 6+ compounds I've tried. I don't sell Carbotech, so there is no vested interest in promoting these.

Agree with the others here...check the pads first. Then check the caliper for proper functioning. Lastly, bleed your brakes:

After a day at the track --> clockwise track --> trailbraking --> boiled fluid marginally on front left caliper but not (as much) on front right caliper --> car pulls to right side under braking because air in left caliper compresses and doesn't clamp as hard on pads as the right caliper, which doesn't have (as much) air in it.

Good luck! -Andie

There is this one stoplight where the car always pulls violently to the right. At first I thought something was wrong but it is a road with a bad rut.

Must be the one at 1600 Pennsylvania Avenue.
