So yes it's not really a project but I legitimately can't think of a better word right now (sleep deprivation kicking in). Anyways... After Part I (And So It Begins...) that can be seen here, where I replaced suspension bushes, anti-roll bars and the recirculating valve, it is now time to change what I feel is the weakest part of the car: the brakes.

It was on my little jaunt across Europe last year, that the problem was made very apparent to me. I suffered massive heat fade and plumes of smoke from the front wheels while on a spirited (though not outrageous) drive through the Swiss Alps. They weren't much better up Stelvio Pass and would only last for one lap of the ring before they would fall over and need a good long rest. Bear in mind I was nursing the brakes around the ring after my previous experiences and it was wet so it wasn't terribly hot. With my intentions of returning to the ring and getting involved in Track Days, it was clear the current system was simply not up to scratch.

After debating with myself and others on the best course of action I finally took the plunge and purchased the following:

They are a set of reconditioned Brembo 4-Pot callipers from a Leon Cupra R. I won them on our favourite auction site as a full kit for a paltry £500. The kit consisted of reconditioned callipers (looking in great condition), new disks (standard plain), new stainless braided lines, new Red Stuff pads and all necessary mounting bits. A kit like this new would set you back typically over £1000 new and the callipers are quite sought after, so I think I got a very good deal. Especially considering a previous auction I was watching consisted of just the callipers in used condition (clearly marked up) without any other parts and that went for £450.

Although the disks and pads aren't what I was originally planning on buying, my budget doesn't quite stretch to replacing the disks and pads with what I really want (EBC Ultimax disks and Ferodo DS2500 pads) just yet so I will make do with what is arguably not a bad setup as it is for the time being.

As mentioned in the previous thread I have also purchased some Motul RBF600 brake fluid to compliment the kit.

The new setup will be installed in the next week or so and should make a massive difference compared to the somewhat lacklustre system on it currently. Once on, I can seriously start contemplating my trips to tracks and of course the 'ring. I can also now plan the next upgrades, where I finally up the performance with a remap and other associated bits.

More photos will be posted once the kit is on. :)
 
Sure those are off an LCR, i didn't think the 4 pot brembo construction of the LCR was monoblock, look like they've come off a Boxster, got a picture from the other side (top of pads down)?
 
LEt us know how you get on with the red stuff pads.

My last set (on there when I bought the car) basically ruined a set of £500 discs and faded awfully...

I've never looked closely at the LCR blocks before. I do think they are monoblock, but I think you're right, they don't quite look right. Something fishy going on here. I need to have a closer look at them I think. They're at home at the moment.

Edit: After a further look, the retainer for the pads (is that what it's called) as seen from above the calliper matches that used on other LCRs. The Boxster Brembos look different (according to google image search) and they definitely aren't Big Reds (I wish). Maybe they're a slightly different generation of LCR Brembos? The ones I've got appear to have bigger pistons?!?

Like you say the top of the LCR pads are different from the boxster, also from what i've seen the LCR has four hex bolts holding the two sides of the calipers together, but they may have used different calipers i suppose.

These are mine :

Pads look like:

Will be interesting to see what you've got, apart from your caliper bracket spaces them out for larger discs .

Edit: actually scrub that, yours seems to have larger piston's

I'll get some more pics online this evening and maybe then I can have a hunt to work out what they actually are. I'm a bit of a noob, so how do I get the pads out of the calliper? Maybe I can search by what pads have been put in?
 
Depends on which calipers you actually have :p

With mine you remove the split pin and bash that pin out (you can just see it in the images) single spring comes out then all being equal the pads slide out.

With yours you might have two retaining pins one top and one bottom of the pad, similar procedure however.
 
OK the closest I've seen to these so far is off a Renault Clio 197. That would be rather odd, but I'm still looking!
 
You really need to look at the mountings, when i was looking around most of the brembos from the french cars had the mounting lugs cast into the caliper, on these (same as mine) you need an adapter to make them fit the hub, seems to be a german car thing.

When you get back home you should have the caliper numbers cast on one of the top edges (large flat top side) should be different for each caliper, stick that number into google :)
 
Well I couldn't find any codes on the Brembos but I did find a code on the pad. It turns out these are the front calipers off a Renault Clio 197. Now I'm wondering whether they're worth me putting on. I know nothing about these calipers, so does anyone have any ideas/suggestions?
 
This is quite clearly not a standard upgrade path haha. Renault Clio 197 Brakes on a 2001 Audi S3. I can see a lot of reviews talk about the brakes on the 197 being great, but my primary concern is that I will be carrying a fair bit extra weight. I'm a bit of a noob with all this stuff, so is it really just a case of bigger is better on brakes? The Kit I've purchased was sold as a full kit. The mounting brackets are clearly custom made. The Clio brakes are 312mm as standard and the brackets I've been given as well as the disk mean I will be using 323 mm. I take it the size difference shouldn't be a problem for the caliper? Argh!! I hate getting caught out like this.

Edit: The pad size incidentally is 125 x 71 x 15 (all in mm) if it makes any difference

The renault ones for the clio 197 and megane 225 both bolt straight through into the hub, theres no mounting lugs on them to mount like a normal sliding caliper carrier. Although renault ones will have the renault logo cast into them next to the LH and RH markings along with a renault part number. So these just might be from the same family.

I'd agree with that as they look the same as the ones on my megane 225.
