AP rear pads/discs choices - ?

[Pip1968]

Following someone's post regarding the pins seizing in their caliper I checked my pins. Actually, as she has been holed up in the garage for the last few months I decided to put the rears into Lepsons for a refurbish - £100 a pop each!!. Anyway the pins were fine with a little corrosion around the calpier's recess of the 6mm hex bolt in the form of white powedery residue.

Whilst doing that I checked the rear discs ~ 19mm and the pads 10mm. So is there any cause for concern are they within tolerance, should I replace either or both of them and what are the choices - ? I am still running DS 2500s in the front when not on track but am not sure what the rears are... presumably the same. I do not really want RS29s on the rear regardless of any equilibrium or not.

Incidentally I bought a spare set of RS29s for the Porsche's 350mm discs and only looked at my card statement last week £445.29 . I kind of assumed they would be comparable to those for a CSL with APs.

Anyway pictures below. Apologies for lack of clarity. The first picture shows the material side and the second the backs. Both covered in rust from the discs.

Ps Can someone confirm that the wheel nuts should be torque at 120nm.

Just make sure you do them up to 88lbs/ft..... :whistle:






I'm not sure about the rest, but my pads work until I hit metal!!

Absolutely, scrapping sound is the warning

All ok.

[Pip1968]

I was wondering when you would be along with your scraping tip top tip Shimmy :-D. So any idea on the minimum thickness for the rear discs and what other options there were aside from OEM with an AP set up - PF?.

I have not looked into prices for the OEM one or spoken to BMW as I am abroad now anyway.

Oem minimum rear disc thickness is 18.4 mm Pip.I only know this because I renewed my discs and pads yesterday and the minimum thickness is etched on them

As long as everything is wearing flat Pip, then carry on using them ( with a new set ready to pounce on first sound of a scrape:bigcry::smokin

How thick are they when new then? 20mm?

Yes mate and the fronts 28mm

Stop skim reading my rambling and boring posts..... I am refering to rear discs not fronts.

I assume that you have either made a typo Bounce or you are talking about fronts at 28mm when new. Thank you for further reassurance CraigMillwardCroft (is that triple barrel super posh/rich - ?).

Are most of those with APs on the rear running with RS29s then. I assume standard OEM pads on the rear will be fine too.

Pip :-D

Apologies Bounce I am trying to multi task and have skim read myself - rear 20mm front 28mm when new - noted :notworthy:

RS. 29's all round, even on OEM brakes they make a big difference.
