UrS4 Rear Brake Upgrade

[Wrath]

That´s the nicest option Hap, but unfortunately ilegall in both Finland and Sweden regarding MOT...

[urs4guy]

That's really nice, but do you have any handrake? Can't pass MOT here without it or with a hydraulic one. Need to be mechanical.

Its not mechanical but I can do handbrake turns ala WRC.

Here's my solution. I use 314x30 2 piece rotors and 993tt rear calipers with custom brackets.







Here's a much simpler solution from Apikol:

It´s a good option but you can easily find discs for around 140 € So I don´t want to pay 450 for some adapter plates... :/

I really dont know,but the Phaeton also uses this size.

V10 S6 330mm rear brake disc, urs4 rear caliper with adapter?

I would consider multi pots calipers to improve the clamping force since we're going to

use the customed bracket anyway.

Keep in mind there is a proportioning valve on the rear suspension to reduce braking pressure as the rear of the car rises. The spring connection on ours broke off years ago and we haven't noticed any side effects without it, might be worth testing with it disconnected and see if it improves things for you.

[popdemonic]

Naturally,the brake bias is making the front doing more job than the rear.

[Wrath]

True, then i could be dangerous, but hopefully in theory it should settle both in the rear and the front, but of the force with weight it´s probably wont...

I'm not sure if the diving is only a brake issue on these cars..? What happen when it dives and you have too strong brakes in the rear?

[Wrath]

Thuppu,
actually,i really want the rear brake to do its job more.our car has known to be not a well balanced on brake.i feel the car dives nose
everytime with hard braking even i had stock brake calipers tho.

What do you mean by diving
