Rear disc upgrade?

[chase06]

Hey guys,

After having my car checked over by a non-SEAT garage, it has been advised that my rear discs are changed as they are deemed dangerous. SEAT have said that they will not be covered under warranty (even though the car has only done 9200 miles from new).

I dont fancy getting SEAT to do these as it will cost a fortune (£250 plus iirc). Is there an upgrade that me and one of my mates (hes a mechanic so will have all of the tools required) could fit them? I quite fancy the 312mm upgrade for the fronts once my wallet recovers from this, is there something similar for the rears or is it just a case of getting the SEAT parts and changing them?

Cheers,

The rears do very little work and general opinion is that there's no benefit in upgrading them - just replace with standard discs and pads.

I guess they've mentioned excessive corrosion on the outer edge ? Pretty common.

Last car I had (Astra G SRi) suffered from corrosion on outer edge - used to keep them clean by using the handbrake.

Buy the bits and do it your self mate. Easy job, ive got new discs and pads banging around in my boot. Waiting for my caliper rewind tool to arrive and going to do it one evening in the week. I too looked at an upgrade but decided agaisnt it after much searching on here.

yeah, just drive it in second at 10 mph for half a mile with the handbrake on 1 or 2 clicks to clean them up, it may take more than 1 try but be careful not to cook them

then just give the handbrake a little go at slow speeds once a month to keep them clean



edit, on my first service (5k miles) the dealer said mine were in need of replacement (but not under warranty) so I did what I have described above and they are fine now as long as I keep them from rusting

Ive already done that mate, and now they are worse and grind pretty bad. The are completely shot and the rear offside is starting to vibrate abit if im doing 70-75 and then brake heavily.

Does anyone know the part numbers and how much it will cost for the 2 discs and 4 pads? Cheers

I got mine from a local motor factors mate. Were £58. The caliper rewind tool I have bought was £10 delivered

 

[chase06]

Nice one, thats more like it. Think ill need to make a few phone calls tomorrow and find out what I can get. Im heading to Kent in 2 weeks (5hours drive for me) and want my brakes to be in tip top condition for then

Cheers,

Also, where do you guys buy the 312mm brake conversion kits from?

Done a quick search, found some available but they seem a bit pricey. Is it achievable under £300?

Cheers

i know there isn't much point for braking performance but looks wise i think there is a point, does anyone know where you can buy a rear brake upgrade from as i would be intrested in getting one aslong as its not stupid money!!!

 

[gazjones]

can soure 256 tt and r32 rear calipers and bits and buy some spacers from a company, but stil bit on expensive side for rear calipers carriers and other bits

 

[Mikey_H]

anyone know of anywhere where they sell them?

 

[gazjones]

calipers and that would be from breakers i think ne disks and pads not a problem, cant remember company that does spacers to fit it all onto ibiza hubs

you overdid it and cooked them then

where did you get the rewind tool from?

 

[chase06]

Nah I didnt overcook them as there were no fresh score marks on the discs, and I didnt do exactly as you suggested above. It didnt clear any crap or rust on them at all, I think that the pad is completely uneven and just isnt contacting the surface properly. Obviously in the process of driving around for a year they have completely shot the discs. They have been like this for around 4months now, but I can kind of see where SEAT UK are coming from with the warranty thing. Some people drive like idiots and stamp on the brakes, so of course their pads and discs are going to wear quicker. Some people (i.e. me) are a lot more careful and generally have more mechanical sympathy, dont stand on the brakes. But warranty depts cant differentiate between the two.

It is a shame though, as I cant really afford to do it right now but they need to be done.

Protools.co.uk or .com mate. Is a draper block. Has 7 different patterns so if future proof. Didnt think it was to bad for the money, will just have to wait to see what its like. The postal strike has delayed it getting to me.

Just had a word with one of the guys I work with and he seems to think that it may be the caliper thats dragging slightly causing the discs to score. He also reckons that they are fine, and that I shouldnt concern myself over them as they do very little in real world driving.

My thoughts are that for a car thats done less than 10k miles the condition of the discs are unacceptable. Id expect that sort of wear from a 3-4 year old car, and they would need a change.

I have that many different people telling me that they are shot, and that they are fine I dont know what to believe. All I know is that they grind when I brake (not deafening, but noticeable) and that this adds to the long list of gripe and issues I have had with this car.

There is a design flaw but no one in Seat will admit it ... in fact there is generally a design flaw in putting rear discs on a car under 1.5-1.6 tons .. but it sells cars and is better for balance (drums fade in different ways to discs) so they do it.. Heck I have a 1.0t car from 1976 that had rear discs.. did not stop them from rusting up .. it only worked vaguely as it has a load sensor so it loaded up the rears as much as possible.. most small rear cars do not as the load sensors seize and then cause more problems.. better to just have display brakes set to work with driver only and then never brake harder than that. If the caliper is dragging .. then it needs freed and the sliding pins need lubricated .. but that is all perfect world stuff.
