Hard left turn causes rear left brake to squall. Why?

Ever since I swapped a 94 disc rearend, when I make a hard or moderate left turn, I hear what sounds like the brake squealer contacting the rotor. Happens for a second then stops.

First time it happened, I thought I had left a wheel lose, since I have had a wheel sound like that on a buick regal. Left turn, left side squaled and I found the left front wheel just a touch lose and also could tell by the contact patch on the rotor. So Ive checked that numerous times and the wheel is not lose.

Ive rotated wheels. Noise always at the left rear, regardless of the wheel.

This weekend I put new rotors and pads on. Same noise at left rear.

Could a slightly bent axle cause this? Only thing left that I can do is to put a dial indicator on the axle flange and rotate it.

So if it aint the wheel and aint the pads/rotor, it has to be the axle right? Anything I am overlooking?

Re: Hard left turn causes rear left brake to squall. Why?

Thinking more on it, It almost has to be something causing the wheel and rotor to not sit flush against the axle and letting it flex out during a turn, much like if a wheel was alittle loose. I may pull the wheel and rotor again to reinspect the axle flange. Maybe there is a highspot on it causing to rotor to not fully seat.

Re: Hard left turn causes rear left brake to squall. Why?

That's usually the rotor rubbing on the "caliper abutment" (bracket) right out at the very edge. Usually on the inboard side (axle pushing into the housing).

A washer under the "abutment" at each bolt usually does the trick.

Thanks sofa! $0.25 fix! Not as embarrassing pulling into a parking lot now. Now people can laugh at the paint, not the brakes.

Sometimes it's pretty eeeezy. Sometimes not so much. Glad it was one of the former this time.
