how to fix sticky calipers?

2nd February 2011, 18:07

every now and again when im reversing the car arches in the air like its going over a bump, but what it really is, is my drivers rear wheel sometimes sticks and eventually it will go back to normal, but this is becoming a bit of a problem, im worried incase im on a hill or at traffic lights and if i go forward the wheel will stick, i also checked today and to my amazement i found i have no wheel arches, may this be a factor ??????

not wheel arches sorry, the things inside your wheel bay which acts as a mudflap but its all the way round??

are they discs or drums?

If discs, take the calipers orf and grease moving parts

If they are drum brakes I'd take off your brake drum and dismantle the shoes, then spray everything with WD40 and free everything that looks like it should move, and grease the end of the handbrake cable, then remantle

how do i fix it tho

those are called inner arches I think , they are nothing to do with the running of the car but just there to keep weather and shite away from the bodywork. I get some replacements from the scrappy or it will cause rusting eventually

You don`t use wd40 you use copper grease,and adjust the brakes if their drum brakes you adjust a little ratchet mechanism,check the inside of the drums too to make sure the shoes haven`t scored the inside of the drum.

it will be just damp etc causing them to stick

what you idealy need to do is remove the brake drum check wheel cylinder are not seized or leaking and adjuster then spray brake cleaner and blow off any excessive breake dust ect and rought the shoe and drum up and adjust brakes to suit

or could be a handbrake cable starting to stick

as said above if anything is seized clean up and apply copper grease them up

TThose are arch liners and wd40 should be used around brakes..
What you need to do is strip it all down, ensure everything that should move does move and that there isnt any stones or anything inside the drum.
Make sure the handbrake mechanism is free to move as it should and is adjusted correctly.

Was that a spelling mistake mate?because I thought wd40 should not be used around brakes

i wouldn't use wd40 as thats just gonna have the same effect as if a leaking wheel cylinder and getting brake fluid on the shoe weakening the shoe material and not allowing them to grip properly as they should

jack it up on the rear and get stuck in!!!!! have a good butchers, try turning the wheel yourself both ways and see what happens? its possible it sticks just as bad goin forwards as it does in reverse, its just you wont notice it goin forwards as much, all will become clear.

had this problem with my passenger side rear calliper. it was pulling my car really bad. when the brakes were changed the cap on the calliper wasn't put back in, and apparently all the crap and grit from the road seized the piston and knackered the calliper. £80 for a new one.

I DO use WD40 and it works a treat

also if you've freed everything off properly you dont have to adjust the rachet, one press of the brake pedal puts it back into adjustment [I have found]
