Full Lock Clicking? CS Discs?
« on: 26 June 2024, 22:22 »
Hi

Had my CS discs fitted for a while now and they seem to have developed clicking noise on full lock, have read on a golf R forum that some owners say the CS discs do it, but has anyone come across it?

Noticeable when going into parking spaces mostly like full lock or nearly full lock.  It varies with speed (although I have only done it at a low speed). So faster clicking if moving a little quicker

Normally I would think CV joint with a clicking noise, but its not a strong noise like that and seems more light weight perhaps a ticking sound.

I took the pads out, checked them, then turned the car on full lock when up in the air and spun the wheels, crabbed the discs and tried to rock it on the pins, but not able to recreate it. Sound went away for a week after refitting the pads. Could the pads just be catching a little after the grease dries out? Try a new set of caliper pins to help the caliper slide perhaps?

Read also about pushing away the backing plate but can't see that would help, but might try that at the weekend.

any suggestions please feel free to comment. :)

Thanks in advance

Just to return to this for people coming back in search results down the line.

Took the brakes apart yesterday with the intention of fitting new caliper sliding pin kit just to refresh 5 year old car, and having a look while I was in there. VW wanted £150 for 1 hour diagnoses of clicking sound as its under warranty (something I didn't really want to pay unless I knew 100% it was a warranty issue).

When I originally fitted the discs the hub surfaces was a little rusty and I wire brushed back to bare metal to remove any imperfections on the contact surface (the normal process). A year later and it looks pretty bad behind the disc.  Not going to lie, I was surprised at the level of rust between the 2 mating surfaces in such a short period of time. Several hours later, back to bare metal, caliper pin kit fitted and wiped down the hub surface and bell housing with WD40 to remove the last bits of dust.

The bearing hub surface isn't completely flat and the contact points are only the outer ring and inner ring which are raised, with the indent/gap in the middle able to build up significant levels of rust (in my case). Was this creating a clicking/creaking noise on the 2 piece discs? like this video?

Noise all gone now thankfully but will see if it returns. But the side with the worse clicking had the most rust, will see if its a coincidence.
