Hi all,

My front left brake is in a slightly ' constant on' position. I had te brakes adjusted recently to be rid of a squeak, and after that I noticed a slight power drop an the car wouldn't creep at idle when in drive.

I checked it by jacking the car up at each corner. And the front left wheel would not spin. As I have to drive a few hundred klms tomorrow, is there a quick fix to this? A bolt to loosen slightly?

Oh I should point out that the brakes are the ralliart twin piston system.

Probably a sticky piston or the slider pins have gone sticky.
You need to take the caliper off first to investigate.
I am not on my computer that has the workshop manual.

However, if you take out the pins that the caliper slides on, fully clean them and then regrease with the correct grease.
Clean the slideways that the brake pad metal backing plates run in.

Try pushing back each piston, there should be some resistance. If there is a lot then it is possible that there is rust between a piston/s and the caliper body.
You really need brake experience before you attempt to work on this part of the brake system.

Front brakes are self adjusting - unless the pistons are seizing on, or the pins are seizing. There is no "adjustment" bolt.

I agree! OP's post doesn't give me great confidence he knows what he is doing.

What was adjusted?
The stop position of the pedal or the hinge tightness or spring firmness of the pedal,
or something on the calipers themselves?

Can you pull the pedal up towards you more than it springs back itself, and if you do does the wheel free spin again?

Who adjusted the brakes the first time, talk to them about it?
