What are the shims for?

Are they important?

The R33 GTST calipers I bought do not have shims like shown on page EN 32 of the R33 manual.There is only one outer shim A and half outer shim B. On the inners there is only half a shim B. The half shims appear to be die cut, ie manufactured that way, not cut with snips.

Any help please.

I used the shims in my last GTR brake upgrade; no squeal, but that could easily be pad related.

As has been mentioned; you can paint on a compound and most decent performance pads now have an anti-squeal compound on the backing plate.

I've heard people rabbit on about how they reduce heat transfer to the pistons; but thats bollocks.:whistling:

That is all great info. To shim or not to shim, that is the question.

On the shims I have there is a sort of "goldish" grease. Is this the anti squeal compound?

So the mechanic is due at 7.30am, tomorrow so I will replace the shims as they were

Thanks for all your speedy input. This is what the forum is for.

Yep, sounds like Coppercoat or similar. Any nickel or copper based high temp anti seize compound works quite well.:thumbsup:

Sets of replacement shims; http://www.ebay.com.au/itm/190431872363?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

The critical ones to have are the corner shims (centre of pic); these are the ones that stop the pads knocking around in the caliper. They go on the thrust edge of the pad.

      High temp brake fluid?

      By robbo_rb180 · Posted

      I use the penrite 600f in my cars and have had no issues even at Townsville v8s when I drove that but I bled fluid end of day for just in case. Good value and a about 38-40 on sale. Use castrol srf on the supercars and no need to Bleed brakes over a race weekend. Do the 1000km with no issues. Over 120 a bottle I seen at repco. A quality brake pad is always a good starting point the ebc stuff I've seen let go after 2 sessions with heavier cars. I'd be going to a decent track pad and maybe those porsche air guides on the control arm to help with some air over the rotor. Helps on 86/brz with stock callipers.

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣
