Just bought a 95' SAAB 3 days ago, and today I noticed a grinding noise on
the drivers side (left) front wheel. Thought it was the brake shoes (or lack
of), but have 90% shoes.

However, there is a worn spot on the caliper, and a matching ring on the
inside of the wheel.

Only grinds when I apply the brakes. Any ideas?

Not shoes, pads. Shoes are the things you get on drums.

Either the caliper is not firmly attached (grab it, push/pull -
does it move?), or you have aftermarket wheels of the wrong size.

My bad, I know better than that :-)



I have tried........unless it is frozen in place....


They are stock SAAB wheels.......

Look at it this way. You say that it only rubs under brakeing.
That means that the wheel moves closer to the caliper, but only
under brakeing.

In order for that to happen, either the caliper has to move
relative to the hub carrier, or the wheel has to move relative
to the hub carrier.

If you're sure the caliper isn't moving, then it must be the
wheel. If we assume the wheel is firmly bolted on, then it can
only be the wheel bearing.

Test the bearing by jacking up, grabbing the wheel, and
pushing/pulling. Any play? Rotate the wheel. Any grinding?

So, I went to the SAAB place today, which was the place that I bought my
car.

It just so happens whoever replaced the pads failed to replace the retainer
spring on the outside of the caliper, which was allowing the caliper to
slide forward when I applied the brakes.

Problemo solved!

Had a similar problem on my 9000. It was down to the balance weights on the
wheel being in the wrong place. The calliper was hitting them.

It ended up being the spring clips on the caliper. I had just bought the car
and the brakes were new, and the clips were left off, allowing the calipers
to move forward when the brakes were applied.
The dealer fixed it for free..
