A160 brakes problem


I have a Mercedes A160 Model 2000 Petrol. The car's been stationary for a good few months. Recently when I tried to move it, it wouldn't budge. I got the jack and checked each wheel and it appears that the passenger side wheel moves freely until I apply the brake. Once the brake is applied, it won't release the wheel for a few hours.

I wanted to apply some WD40 somewhere but am not sure what's causing the brakes to not get released when the brake pedal is released.

Would really appreciate someones advice.

No - don't do that.

I assume that you are only talking about the foot brakes here. The parking brakes are not causing a problem, right?

It sounds to me that a brake caliper needs attention. With neglect (or non-use) the pistons inside the caliper can get seized, causing your problem. It may be possible for the bad caliper to be cleaned up and made good again, but otherwise if pitted with rust you might have to replace the faulty parts.

Basically, since this has happened to one brake caliper, I would suggest that you need a comprehensive brake service now on all four wheels, and with any bad parts replaced.
