Impreza 1993 , automatic , 4x4 , about 200.000 Km.

 

From time to time (but it is getting more frequent) it squeases at any speed ,

at every turn of the wheels , but it seems to originate from the right back-wheel.

 

If I put some pressure on the breaks (even without a real effective breaking still) the squeazing stops ; after leaving the pressure , it starts in few seconds again.

 

Hanging brake pads ?

Who had the same experience and could give me a hint ?

 

thanks , Hendrik

It sounds as if you have a sticking piston in the caliper of that wheel, or the brake pads are sticking in their mounting bracket, or the slide pins on the caliper are sticking. All three circumstances will result in a screech/squeal situation that can be made to stop momentarily when you apply the brake pedal.

 

When you apply the brakes, the pads clamp onto the rotor, but are released immediately and move away from the rotor, when you take your foot off of the pedal. In your case, the pads are clamping onto the rotor, but can't completely release, causing the noise.

 

You need to get them attended to immediately, before you have that wheel lock up and strand you. At this point it will be far cheaper to correct than if you wait. Good Luck!
