Cupra/Boc Upgrading Brakes

[Deleted member 55317]

I've seen a few folk asking about whats needed to upgrade the standard cupra/boc brakes soo....hope this helps. I replaced my standard Cupra 288mm brakes in Feb.

The two simple options are the 312mm AP Racing brakes from SEAT themselves. They are quite pricey though! Get these from SEAT and a decent mechanic/yourself to fit them and your laughing...but...if like myself money is an issue you can go for the 323mm 4 pot Brembos off of a MK 1 Leon Cupra R/MK4 Golf. This is what I chose.

For the SEAT set speak to Sere Motors on here they'll keep you right with what you need.

For the 4 Pot Brembos you need

2 x Calipers

2 x Discs

4 x Pads

2 x Carrier

2 x 10mm Hubcentric wheel spacers (I got them off DPM performance on here)

10 x Extended wheel bolts (again DPM made sure I got the right size)

You can get the full kit off ebay (minus the spacers and wheel bolts see dpm like I did if u want) and it'll set you back around £525 now. Search for:

VW/AUDI/SEAT/SKODA 323mm MK4 GOLF TT S3 BREMBO CALIPERS

and the right ones will come up depending on whats on at the time there is sometimes a choice of colours.

WARNING The 312mm Brembos for the MK5 Golf do not fit as we have different hubs!! Dont mix these up with the 312mm AP SEAT brakes.

So one youve bought the kits get the spacers and wheels bolts...Hubcentric if you can! They set me back around £100.

Get the kit fitted by a decent mechanic/yourself the brembos and seat sets are both direct replacements...un bolt the old, bolt on the new!! and allow the brakes to bed in.

I have replaced my front pads with EBC Green stuff pads as the old ones were squealing bad due to LOTS of dust

I highly reccommend this upgrade as I have never looked back and my brakes now tear my face off haha!!

My RR descibes some teething probs I had due to SH!T weather and an even SH!TTER mechanic! but all is good now.

When i spoke to a friend of mine who I consider quite car savvy, he mentioned something about master cylinders??... and how just upgrading the hubs and discs isn't enough and you can end up doing more harm than good in the long run...?

How much of this is true and sounds right?

as far as im aware the thing you need to watch out for is that the master cylinder can cope with the pistons on the calipers. the seat sport brakes have the same master cylinder and my master cylinder copes fine with my brembos. I wouldnt fit 6 pots on a standard cylinder but it can deal with 4 pots

I was under the impression the mk4 R32 had twin pot calipers and not 4 pots. Was it not the mk1 Leon cupra with the 4 pot calipers?

Also you say you have fitted 323mm discs, did you need different caliper carriers?

My brembos are the ones off a MK1 LCR and yeah it needed new carriers. carriers bolted to the car, calipers bolted to carriers lol

can you explain the carrier situation please. SO if I buy another branded caliper that fits a mk1 leon/mk4 golf, e.g a tarox or a hispec, what carriers do I need. VAG ones or ones from that brand?
