Title: changed Pads, now caliper touches inside of alloy
Post by: Diluxe on 26 July 2009, 09:57
Hey guys , I can't fgure out what i've done wrong.

I've just changed the pads on my mk3 16v (288mm), and the pads have moved the caliper close to the inside of the wheel that wheni bolt the wheel back on it, the inside of the wheel spokes fit tight up against the caliper body.

Happens on both sides.

This is the 1st pad change since i've had the car, and I've got the anniversary wheels on ET 42

any ideas?

cheers

Are they very close or touching?

Had this exact issue with Guy's car, he's even running the same alloys. We just filed back the casting marks on the calipers and all was good.

As above, file / grind back or run a 3mm spacer.

hmm thats mega weird, that you guys have had to grind the calipers a little,

surely the pads on the anni Golfs cant have been different from factory? from the standard 288mm pads?

I'll have to get a spacer.

Wheels were clamped shut against the caliper body, got a nice grove on the inside of my spokes  :smiley: :cry:

this happens lots when fitting the mk4 6.5j et42 wheel...the gen anni alloys are 7j with an et43 offset, its not much but it does make a difference!! (hence grinding a few mm off the caliper)

sorry to sound dumb but did you push the piston all the way back into the caliper ?

lol sorry i forgot that golfs have stationary calipers.

on my old car the calipers used to get pushed outwards ever so slightly. good old french cars

I have already said "its because he's using mk4 rims which are narrower and have an offset of et42"....it makes a difference as when on std wheels the calipers are close to the wheel that et1 and half inch means they get snug (too snug sometimes)

You are correct...but the design of the rear of the spokes are different 7" ET43 to 6.5" ET42.
The offset shouldn't affect it, nor should the width, if the rest was the same...but they aren't.
The curve on the spokes is different between them.

But, as you say, that's the problem.

That is the problem- rub the pads down like people do when they end up with g60 pads trying to fit them to there 16v set ups- Gurds has had to do this to his ds2500 when they sent them in error and it was too close to track to do anything about it. use a belt sander
