View Full Version : Upgrade Rear Brakes to 256mm Vented
Driving by a local junk yard and found a 2001 Cupra4 with a very smacked up front end.
I've been looking to upgrade the brakes on my Toledo TDI 150??
Started wondering if I should pick up the vented rotors and calipers from the cupra4 which are in great condition????
Not that I dislike the brakes on the Toledo, but I don't like the feel of them when comparing to by previous beeza. They feel spongy.
Figured I'd upgrade the front to the 312mm A8 brake rotors (just need the rotors and caliper holders since brake padd area is the same). Really not sure if the rear upgrade is as important? Has anyone upgraded there rear brakes? Will the front upgrade be enough? Thanks for your input!!:cheers:

rear brake discs are only there as stabilisers to stop the car from getting out of shape, they only use about 15-20% of the entire braking force used in the entire system, the rear ones of all 16v vag cars look small but they certainy do their jobs well enuff.:cheers:

Surprisingly my rear brake pads wear off at 20000KM.
The mechanics applied too much pressure while servicing brakes.?
a few of us in Singapore are having this problem.

The Leon Cupra, and Toledo V5 have 312mm front disks anyway, and I'm sure if you check the Seat.com site, so does the TDi150???

Had already checked....The unfortunate answer was Not !!
Checked the catalog as well as actually measured them (to the best of my ability). and 288mm they are.
I can't really complain about the braking it seems OK for now, except the mushy (spongy) feel it has when compared to my beeza. But!!, as I get more and more used to the car, I start pushing it more and more to its limits, better braking is a good idea. (still debating if I should chip it or not ?? but that a whole other story ;) ).
Maybe I should just upgrade to the 312s now and latter upgrade to tarox disks & SS brake lines? That what I did on the beeza.

20000KM ???:sick:
That's worse than bad. I do mostly highway driving, but on my old beeza GT TDI I was getting 70000km front and the rear was changed once at 215000km.

if you brake too hard the rear end should not try to step out on you, f it does then they need adjusted a little bit and bring the bias back to the front a little.:cheers:

170bhp Toledo has bigger discs all round than 150bph version. Don't know if they are the 288mm rotors you mentioned. Would like to know the results if you do put bigger discs on. Mine get very hot and smelly with what I would think is little reason. Would also like to hear from anybody who has fitted drilled or scored discs. Have done a lot of motorway miles in the rain this winter and numerous times the brakes have had difficulty getting through the water accumulated on the surface of the disc. I push harder, with little improvement in braking then all of a sudden surface tension is broken and anchors are full on :(

The 170 comes with 312mm up front (like the A8s I picked up) & 256mm vented rear. The 288mm you mention was on the older 150 V5 and on the present 150 TDI. The difference between the 288 & 312 is size only since the caliper and pads are the same (aka same pad to disk area), you get better braking with the 312 because of better heat disapation and greater linear velocity.
I haven't installed the 312mm yet but will soon. The rear however are the very tiny 232mm solid disks (you can bearly see the caliper with the 17" cupra 4 wheels:( )
I've got the slotted/drilled tarox sport japan rotors on "now mom's" opel corsa. Very good improvement over stock. However I've began to notice big cracks starting to develope from the drilled holes. Next time I will probably go with only slotted rotors.
The difficulty you mention when going through water has only happened to me after washing the car.

Not sure if this is a case of different markets getting different braking systems but my old UK 150hp Toledo V5 most definately had 312mm front disks and 256mm rear exactly the same as my current Leon Cupra. :eek:
