Caliper size for Rear Calipers for non PP GTI

I'm wondering if anyone out there has tried to upgrade the rear calipers on a standard MK7 GTI at any point. I recently upgraded the front brakes with PP Calipers and some ECS 2 piece rotors. I went to do the same with the rear however the parts I ordered turned out to be for a manual hand brake rather than the electronic brake. I"ll need to return the rear calipers as they aren't much use to me but does anyone know if there is any difference between the PP and Non PP when it comes to models with the electric rear park brake? Eye balling the rear rotors at the moment and the braking surface area seems to be identical which suggests the rotor diameter is the same, of course the rears are solid and not vented unlike the replacement rotor's I have so it's a different thickness (22 vs 10).

You'll need the caliper carrier as well as the caliper it's self.

Part numbers are;

Caliper carrier: 5Q0615425
Caliper left: 8V0615423A
Caliper right: 8V0615424A

Hey Guys, had a read through the thread first and didn't really get an answer so i thought i'd post away.

Got a 2014 MK7 R, 45000 Kms and VW mentioned my pads are low but discs only 50%. 2 weeks later the MFD is indicating low pads. (surprise surprise)

Rather than just throwing some new pads to get by, i was considering doing an upgrade on the disc's & pads (front only for now). I dont want to create any noise(squeal) or additional dust to standard but wondered if there is the an aftermarket street performance disk,pad arrangement that is trending as a good choice for my car.

No Track use, just daily spirited driving, intend to get a stage 1 tune by end of the year it would be good to do some future proofing

Thoughts?

Cheers in advance

The ATE Ceramics are probably your best bet, but price them up first.

Actually, PM me your details since you're in Sydney, and I'll see what I can do.

My 08 GTI wears the rear pads faster.

Don't be a cheapskate and do fronts only - do the whole car.

Yeah thats true the vw's apply the rear's 1st under normal light braking i have gone though 2 sets of back brakes vs 1 set of fronts in my mark 6
Getting a mark 7.5 this week been looking at a bbk or upgrading rotors/pads but have called several vw performance centres in melbourne none of who have bothered to get back to me maybe they think i am just a tyre kicker? disappointing as i want some further mods including coilovers and tune further down the track and would use the same company that helped me out with brakes... oh well will just paint calipers atm for a good look and upgrade later when i do coilovers and tune maybe they will listen then

Thanks for the feedback all..

I'll go flash a torch on the rears and have a look.. although my VW Service only mentioned the fronts, which is strange if the rears grab first..

Too much driving in reverse [emoji16]

What disc with the ATE Ceramic.. I've used the DBA Slotted in the past..

From all i have read the dba t3/t4 slotted seem to be a good pick

[Umai Naa!!]

ATE recommends their own discs, for optimal performance.

[Kachingg]

Yup i bet they do
And all other's are inferior i bet hmmm
Do your research fit what you think is good for you all have pro's and con's usually price with aftermarket rotors

Hey, just had a 60000klm service done and my mechanic said I've got huge grooves on just the inner of both front rotors. I did not get to see them but I put my hand over and felt, the seemed very deep. Car brakes ok with no squeaking.
Anybody else had this? I'm seeing if VW will cover this under warranty. Funny thing is there is plenty of meat still left on the pads. I don't drive hard.

The oem rotors are made from a soft iron to pass the eu test for stopping with cold brakes when the brake booster fails
That said 60k is low for that to happen but you have a r so i bet the vw warranty people will go hard driving/it's a wear item
Ect did your mechanic say they needed replacing?
If not keep using them also usually the oem brakes have 1 or 2 pistons on the inside of the caliper that press against the rotor and the other side gets pulled onto rotor
That can also lead to the wear you are seeing
If vw won't come to the party with replacing them
Get some aftermarket dba/rda ect rotors more expensive yes
But much harder iron plus better looking if you go for the slotted look
Let us know how you get on with the warranty claim

Thanks for that mate. Yes I bet they say hard breaking, which I don't do as there is plenty of meat on the pads left, still worth a try. My mechanic said they are fine and it breaks fine, as if he had not told me I wouldn't off noticed. Yes it will be some T3's and remsa pads sooner rather than later, even though it's fine I still know it's there. Booked in at VW tomorrow, I'll let you know. As I say, pads are like new and the outer of the rotors are perfect. It's just both the front insides.

Ok. According to VW these deep grooves are suppose to be there, it's how they balance the rotor?? I'll try and get some pictures next time.
