BREMBO BRAKES

[MarkB]

Not saying I am not listening to Corey, I just dont understand why its never been raised before? I done a hell of a lot of reading into the brakes before I decided on a purchase and never encountered anything. Even searching about now I am not turning up anything.
Lets be honest here, I am most certainly not the first person to have a set of ECS brakes am I?

I know S4Woody has ECS as he helped out when I was looking for wheels to fit over them. I am pretty sure he "knows his stuff" too.
Rikrose and Nige too all commented on how great their S4s where with ECS 4s, but dont recall anything about "but you need to turn them around because ECS are crazy"

I know your pain. I've been looking to fit these calipers as per Jimbo's setup and was about to ask about the caliper needing modifying (swapping) then Jimbo asked the question for me.

[Corey]

Alright calm down. No need to get all arsey about it! And certainly no need to wish ill on peoples families is there.
Gods sake people on the internet are a funny bunch of gits over simple questions. "Oh no don't you dare question me RAAAAAAR!!!!"

I was SIMPLY ASKING THE QUESTION BECAUSE I WOULD LIKE TO KNOW WHY YOU THINK THEY ARE UPSIDE DOWN? Why you think a respected Audi tuner would put them on upside down. Why you think ECS would send out probably thousands of these caliper sets upside down. Why you think that everyone who has installed ECS stage IVs (near enough the same caliper as above) has never mentioned they needed to switch it around.

It really goes against what every one else is saying. Thats why I asked.

I was not questioning your motives or your work location or trying to invoke an argument. Seems I got a whole crapload of those things though eh?

Incidentally they are not removed from a vehicle they are brand new as purchased from ECS.

I apologise if my post came across as harsh but I was trying to hammer home a point, please remember the written word is without emotion (certainly from keyboard anyway).
I would as anybody who has purchased a brake upgrade from anywhere (ourselves included as we are not without error also) to check the orientation of their calipers (following safe workshop procedures).
If indoubt take photos and ask.

Interesting thread. Do the 4 pot Porsche 993 brakes have different size pistons?

It sounds like there is a quick method to check orientation? Is it which ends the bleed nipple is?

No worries mate, I probably took it a bit wrong as I was in a bit of a mood last night (comes from dealing with some of our stupid customers sometimes - I was working on call yesterday and that I was thinking I have blown £1600 on brakes + £1300 for wheels to be told that they may actually be useless for my car).

I do thank you for the assistance though as it would certainly seem you know more than even the companies fitting these products and more worryingly, those who are "creating" (re badging) them!

Given ECS response to the question and the evidence from those with the RS6 setups (which are near enough essentially the same calipers), the pictures of Alcon/Stasis setups and AP Racing setups we are going to have to say that ECS are indeed wrong and supplying the product not in its best configuration.
Unless of course the plan is to tie you in to buying their pads as they wear out quicker and seem to be going to some lengths to hide what the components that make up their kit actually are? Maybe I am being silly there, just an opinion

Good news is that the pipework and nipples can be swapped around easily enough with no need to machine the caliper body. It does look like you might have to because of the recess cut out at one end, but when trial fitting it last night it goes straight in with no bother at all.

Would still be nice to get ECS onboard though. If the implications are just uneven pad wear then no real big issue.

[DavidT]

You won't get maximum performance if its wearing the pads unevenly because the pressure across the pad is less uniform. I'm not sure by how much, it may be marginal, but outside the calliper design for sure.

It's not the first time I've heard ECS making a cock of their brake kits either

Corey knows his stuff, I've bought from him and had prenty of free advice

[Corey]

There is no need to machine anything on the caliper when swapping the crossover tubes. Even though there is a recess at one end to hide the rubber protection pad on the crossover tube, it fits perfectly when the swap over is done.
I can do a pictorial to show the swap incase my write isn't understood fully? Please ask if in doubt.

99% of all multi piston calipers have different sized pistons so the pad wear is even.
It is not nipple dependent on whether the small piston has the lead, it is whether the caliper (in its original fitment) is a trailing or leading caliper.

Indeed - from experience don't take any advice from ECS, let alone bother buying anything from them - particularly brake kits.

thanks for everyones input on this suject and i think its prompted a few people to go and check the caliper configurations on their own cars and swapping round if nessecary. brakes are the most important part of the car so im glad this has been thrashed out. when i get the threaded caliper back from the machine shop on tuesday il post another pic of how i modded the top hole to get it lining up on the disc right for anyone wanting to go down this route.
i can only assume that rs4 discs are 350mm in diameter as std as no one seems to know anything about mine being modified, so if anyone has an old or new disc lying round please can you measure itand let me know.
next up i just need a little advice onwhat pads to use , a part number and where to get them from. im thinking of getting some oem cayanne pads but darent get a price from a porsche dealer, audi are bad enough.

Hey Jimbo, have a look earlier on in the thread - Page 3 halfway down. I posted the part number for my pads which are Cayenne models and also a link to a website with other models from different manufacturers so you can cross reference them easily enough.

[jimbo1234567]

thanks for that. must have missed it during my fortnite of doom, gloom and depression. the anti depressants have kicked in now and i feel fine again

[jeffw]

Try and get a set of Ferodo DS2500s for your calipers

AFAIK they aren't available, though if they are I'd be interested

[jimbo1234567]

ive just ordered a set of mintex pads off of the bay.

[rikrose]

Well this is a fun thread to come back to after an absence. I need a 4 wheel alignment at the moment anyway, so I guess when I do that, I'll ask them to take off my pads and tell me which way around mine are. If they're the wrong way around, I guess the question is what we can do about it...
