Graham W Posted October 12, 2017 Report Share Posted October 12, 2017 Just about to replace my front discs and pads and I'm wondering what I should torque the calliper bolts to? Also any idea how long it should take to do both sides? Thanks in advance. Link to comment Share on other sites More sharing options...

chrishak Posted October 12, 2017 Report Share Posted October 12, 2017 If all fixings ondo without problems and you have new hardware to hand e.g. caliper bolts, disc to hub screws and a fitting kit (the latter mainly for the 'R' clips), 2 hours tops. If, on the other hand, a caliper bolt shears or a disc screw rounds off, your guess is as good as mine... Are you fitting new anti-rattle plates? I used my old ones, didn't glue them to the pads and they seem fine. Link to comment Share on other sites More sharing options...

Richard Hamilton Posted October 13, 2017 Report Share Posted October 13, 2017 Sorry, but the 981 wheel bolt torque is 160Nm. It actually changed from 130Nm from MY2012 (including later 987 Gen 2 cars). Also notice the new instruction about not greasing the bolts. Link to comment Share on other sites More sharing options...

Ah yes I was only aware of 987 values and selfishly and without any further thought stated that value. Useful to highlight the difference moving to 981...

Graham W Posted October 17, 2017 Author Report Share Posted October 17, 2017 Thanks for your help. I did the job over the weekend with only one niggle. As I undid one of the caliper bolts it also removed part of the thread and so had to retap the caliper but apart from that all's well. The attached photo shows why I was experiencing brake judder whilst driving through the Alps last month. As you can imagine the pads were in a poor state!

daz05 Posted October 18, 2017 Report Share Posted October 18, 2017 Any idea why the thread came away, where the bolts corroded In position? Link to comment Share on other sites More sharing options...
Graham W Posted October 19, 2017 Author Report Share Posted October 19, 2017 As you can see from the pictures the discs were pretty badly pitted and corroded and I therefore suspect the bolts had suffered a similar fate. I put this down to the previous owners usage of the car as I picked it up as a 4 year old, 1 owner car with just 12K on the clock supplied by a Scottish OPC and so I guess it sat around for a lot of its life in a cold and possibly damp garage with brief runs out on fine days? Only one of the bolts actually stripped the thread but all had to be gently coaxed out and replaced with new bolts. Link to comment Share on other sites More sharing options...
