How do i change the brakes on a golf Mk4?

Answer 1

The front brakes are held in place with two Allen bolts running from the back of the brakes to the front. They are hidden behind black plastic covers. Flick off covers and undo the7mm Allen bolts and remove the same.

Wriggle the calliper until it comes off in your hand but don't allow the weight of the calliper to be supported by the brake line. Tie it up with a piece of string.

Pull the pads out from the clips and disgard.

Undo the brake fluid reservior under the bonnet and allow it to sit on the top of the neck so any excess fluid can run free when pushing the callipers back in. Ensure you don't get the fluid on your bodywork as it will strip the paint off.

never Use a G clamp to push the piston back in !but only a couple of millimeters as you may damage the seal. Just enough so that with the new pads in place you can fit the calliper back snuggly over the disc.

Ensure you have used Copper grease on the pad springs.gsf pagid copper replacement grease !

One fitted back onto disc snuggly replace the Allen bolts and tighten.don't forget the spring clips otherwise pads will chatter in calipers !

Repalace the reserviour cap and pump the brake pedal slowly until the pads reset onto the disc. Don't push the pedsal all the way down, just an inch at a time until you have firm prake movement.not needed till all together and fluid cap back on ,

The rear brakes are similar but you have to wind the pistons back in using a special tool. You can use mole grips to turn the piston clockwise until it goes in just enough to enable the calliper to fit back over the disc with the new pads in place. Take your time and everything will go to plan.poss front pistons will require winding back as well depends on model ..and never use mole grips that will definitely dammage the seals !
