Title: 16v Gti front brakes dragging
Post by: james_nich on November 02, 2025, 04:25:28 PM
Hi all, I've changed out the old front pads and discs after a solid few years not moving.

Re greased the slide bolts with full wind back of piston and good clean up.

Pumped the brakes back up and they seem to be dragging a lot. Near side a bit more. Almost like they aren't backing off fully.

Not entirely sure why. Anyone have any ideas? Servo maybe?

I think you should check the piston are not sticking.

Hi there, I wound the pistons right back and pumped them back a good few times (without pads and off the carrier) to make sure they weren't binding. Both moved freely out and were quite easy to compress back in.

Hi without pressure being applied the piston should just relax and let the disc spin freely they always just touch very sightly.

Are the wheels hot at all after a drive, like really hot or just warm?

Before I changed out the discs and pads they were extremely hot. So decided to give them a service as above.

Figured it might have been jammed slides or pistons but everything seemed very free to move when put back together.

Now they are binding but not as badly.

Sounds like you've picked up a little grit or something in the piston.
Could be that they've started to corrode as well.

Fortunately rebuild kits are pretty cheap and you can do them yourself without too much trouble.

Fair point, the callipers on the front have got a lot of years on them, maybe even original. I'll have them off and rebuild them then!
