PR CODES
- Thread starter raptor120
- Start date
I was going to say that it should be in the front of the service book but I supsect you didn't get one with your car.
A Seat dealer should be able to give you a print out of the PR codes for your vehicle.
Maybe as a starter, from the records and CAR DATA for my daughter's May 2019 SEAT Leon Cupra, the fronts are TRW with 340 X 30mm vented discs, PR code 1LJ or 1LG or 1LD - the printout of CAR DATA for that car lists front brakes as being PR - 1LD silver callipers - but Cupra has Black callipers, so nothing is straight forward. The rear brakes are ATE with 310 X 22mm vented discs, PR code 1KY other comments are "no wear indicator system" - or similar wording.
Edit:- as a VW Group parts listing I tend to use now only lists PR-1LD or 1LJ and callipers colours RED or Black - really for parts like discs and pads PR - 1LD and PR - 1LJ use the same parts.

Out of interest, is it the rear brakes that are needing immediate attention, ie totally worn down pads?
Unfortunately, it seems at least on that Leon Cupra, that one of the "speed control" systems uses the rear brakes, and uses them quite heavily, my daughter's Leon Cupra is a May 2019 reg'd car - it was pre reg'd so only used and sold in August 2019, Covid has meant that its daily use was near zero and so it is only at maybe 14,000 miles run in total, and the rear pads are down to maybe 5mm, as far as her SEAT dealership has reported, I used my reasonably recently bought (a father's day present) Laser Tools brake pad material measuring tool that lets you get in through the alloys and get a measurement of the friction material - I measured these outer pads as having nearer 3mm of material on them! The SEAT dealership did not stock pads for that car so was not trying to sell her extra, but maybe essential work - same for front diff servicing!
I'm sure vehicles with Electronic Parking Brake wear the rear pads out quicker than cars with manual handbrake!
I'm not too sure, most of the "holding" of the car when driving around should be coming from the "hill hold" or "hill assist" which just operates the valves in the hydraulics and holds the car using that and not the electric rear brake motors operating.
I've read "somewhere" that it is mainly the car's speed control system(s) that use only the rear brakes to trim the speed - by using the ABS pump and valve block maybe. Certainly, it seems, cars mainly used within city limits, ie with stop<>go driving, seem to the cars that need new rear pads and end up with maybe "blued" or discoloured rear discs at lower mileages than cars mainly used on motorways - but there again, that will be true for any car brake systems I suppose, it is just that these cars end up with a lot more rear pad wear when used in cities most of their life.
