Brakes!!

what size wheels are on it mate?

looks like the 1.9 came with 16's and 17's and different sized discs accordingly

 

[andyj]

16's = 280mm 22mm thick new, 20mm thick minimum

17's = 288mm 25mm thick new, 23mm thick minimum

As far as i'm aware too the setup with bolt on carriers is the 288mm setup which i have on 16" oem wheels.

toxic will post pics as soon as I can ie if I get home before its dark!

Hi,
The wheels on my Altea 1.9TDI reference are 16" diameter

What about the rear discs and minimum thickness?

Also still trying to find out.
Where is the best deal to buy these and typical fitting time?

rear discs: 255mm 10mm thick new, 9mm thick minimum

www.brakes4u.co.uk are failrly good

so are Euro Car Parts, German Swedish and French..... amongst others

Fitting time depends if you've done brakes before.... I can do front discs and pads in under an hour....

The rears are pretty much standard across the board i think, there are two types of pad, so if you can take the old one with you to get the new ones, saves lots of hassle. also, rears need the carrier removal and a caliper windback tool, very useful. Cant remember the size of the bolt for the carrier, it is a 12 point torx key. After that pretty easy to do, I had never done this and after faffing about with not taking the carrier off, I got it done in half hour.

Guys

I was looking at the 312mm brake on ETOS for the Altea. I was comparing the brake part numbers etc from the PR-1ZE and PR-1LJ pages (312mm and 288mm pages)

The brake pads themselves are the same part number. if that is the case then braking performance is exactly the same since pad coverage is the same. Is ETOS wrong? though since the brake callipers are the same then I guess the pads will be the same as well. so upgrading to 312mm discs is looks only.

Just my 2 cents worth.

 

[chungster]

the bigger disc may provide better cooling efficiency/heat dissipation so better performance overall etc so its not purely looks.

 

[CrispDust]

OK we've been over this many times before:
difference between 288 and 312 is just the carriers. Calipers and pads are exactly the same.
So pad area is the same BUT
1. Swept area much larger per rotation of disc so more braking "power" greater heat dissapation
2. Larger mass of metal so greater heat dissapation
3. Much greater torque or leverage available due to increased diameter of disc.
I have noticed a much smoother progressive pedal/brake action, far less snatchy.
I have checked 345mm and 312mm pads side by side - very little difference in size/area

Even as a dealer, this issue has me intrigued. ETKA is not always correct on brake parts and we often find a rummage thru the stock is necessary to find the right pads for a car on the ramp. For example, Mk1 Leon rear pads still seem to crop up regularly on Altea/Toledo/Leon and front pads are soooo hit and miss.
Possibly a bit of the Citroen/Peugeot attitude at the SEAT factory - if its on the shelf and fits the car, stick it on and sod the instructions

Cheers guys for the input. should be ordering some soon.

Sounds about right. Checked mine as am replacing discs and pads, in each part book it states 280mm disc for the 16" wheel and 288mm for the 17" wheel. Mine is 288mm with 16" OEM wheel, that is on a 5P chassis MKIII Toledo.

will 312mm fit on with a 16" wheel?

 

[googies]

Am pretty sure they won't fit as there is ~10mm clearance, if that between rear face of caliper and the inner diameter of the wheel. 312mm is 17" wheel minimum.

 

[Toxic]

have you changed your wheels then? thought you had 17" RS8's

Hi,
I have SEAT ALTEA 1.9 TDI Reference 05 Reg. What size are the Discs and what is the minimum thickness for both front and rear discs.
Where is the best deal to buy these and typical fitting time?

if you want Geniune parts then david @ seremotors, though postage maybe steep since the discs are bloody heavy. genuine 312mm carriers from seat are £104 then + vat! (thats each lmao)

i have mone now just awaiting a good day to fit them though need to confirm pads, since only one new pad has a wear indicator, which seems weird to me. usually each side has a wear indicator.

CrispDust, or anyone can you confirm that each side has a wear indicator fitted to one of the pads?

need to go check mine i guess but doesn't seem right that only 1 pad out of four has a wear indicator.

 

[seremotors]

if wear indicators are fitted, the sensor lead is on the driver's side inner pad.

 

[CrispDust]

Hmm I had a sensor lead on pad but no wire on car chassis to attach!
Weird.
I would have thought brake pad wear sensor where all but standard on any car these days?
