Brake disc sizes

[Johnny Leon]

I've got a Leon 1.8 FR 2016. and am looking at new brake discs. All the parts sites list multiple options for it, eg rear 253 or 272mm, front 276, 288, 312 or 340. Understand each has a PR code to identify it but can't find any info on which PR codes I have. Stickers in boot and in service book have lots of useless PR codes (eg 5SJ - left exterior mirror convex !) but nothing relating to any brake PR codes such as 1KD, 1ZE etc. No websites seem to be able to work off a VIN no. to narrow it down.

Anyone found a way of identifying brake PR codes without resorting to taking wheels off to measure them ?

Is that so hard to do?

I got the PR code from Seat website. Cost me €7. Then it lets you download the full options kit for your car on a PDF, including which optional brakes were fitted

Or ask at your local SEAT dealership for a printout of CAR DATA for nothing.

Thanks Suj999 and RUM4MO, I'll give local dealership a call and see how helpful they are.

You can check brake disc sizes in 5 mins from the comfort of your own home:

Find the PR codes for the front and rear brakes on the PR code sticker on the boot floor / front of owners manual. Use a PR code decoder such as this one to establish the front / rear PR codes:

The Leon workshop manuals are here:

Look at the technical document titled ‘brake system’ that corresponds to you type of vehicle i.e. ST.

You need to look at Section 00 - Technical Data, Sub-Section 3 - Technical Data. There are tables for each of the front and rear PR codes. Item 3 in the table is the brake disc diameter fitted to your vehicle (at the factory).

I see the tables and I have the PR codes but none of those look to correspond with the ones in the tables.
