Title: GT 140 Diesel brake disc sizes
Post by: four! on September 05, 2011, 06:18:32 pm: Hi,

Seems to be lots of choices for disc sizes come up for my 07my gt 140.

I have bought the fronts 288x25

And bought some for the rear 255x10

The rears had a choice of 260x12 but as they are so rusted (and still on the car ) I cant get an accurate measurement.

Can anyone confirm what i've bought is correct? Got a feeling the rears are wrong but parts guy says 255 on the back??

Many thanks

George

Post by: four! on September 05, 2011, 08:07:32 pm: Yes please :wink:, if they are somewhere handy, it's a right pain to try measuring them on the car though. Not sure if i was measuring 2.5mm of rust build up or the actual size, they are so similar :grin:

Do you know if I need to remove the rear caliper carrier? in which case I will need a m14 spline socket?

Cheers

If so you should have 312mm front and 286mm rear.

Thats what was on my 58plate :happy2:

Mine came from - www.eurocarparts.com - with my Briskoda forum discount they were under 23 quid per disc, the part number is: 104441258
