Pads and discs at 20k?

Hello,

I will introduce myself properly shortly. Just been called by my dealer to say the ads and discs on my diesel R Sport need replacing. Apparently discs are badly corroded. I have had no warning lights and 20k and 15 months strikes me as being very early. Am I wrong?

I have done most of my miles on the motorway if that is relevant.

Along with first service I am looking at £1,500. Pretty annoyed right now.

Stop opening the door and putting your foot out to stop it. You will wear your shoes out. :lol: :lol: That is why your brake pads are lasting so long. :lol: :lol: :lol:
:D :D

I do commute quite a bit though.

I actually signed up to see the experience of drivers who've put high mileage on their XEs. I am hoping to keep mine for as long as I possibly can!

I've just had my second service and flagged up uneven wear and rusting on the discs - I'm at 13.5k miles. They said it was normal and nothing of concern. Not so sure myself, there's a permanent 5mm of rust around the perimeter and the disc surfaces have a ripple feel. I find myself looking at other cars and by comparison the Jag's look poor.
Took a couple of pictures today for you to compare with yours.
Like yours, a 2 year-old S and mine has just under 12K on the clock.
Swept part of the discs are completely clear.
Tiny rust lip on the corner edge of the discs.
Outer rims of the discs and the internal vanes on the vented part are rust free too as they have a dark grey coating.
Please feel free to show your dealer to show them it's not normal in your case at all.

Thanks Phil - I have downloaded your photos and will show the dealer - my car's going in at the end of the month...

I have a used XE and a used LR Discovery 4, both of which the dealers cleaned and painted the hubs on all four discs due to corrosion. When you buy decent quality non-OE discs, they are generally 'coated' on the non-braking surface, but I agree, it seems JLR had a period where they weren't doing that, and I see a lot of scabby looking discs on fairly new cars. Should only really be cosmetic though, and if you're seeing discs needing replacing at such short life/mileage, I would certainly be pushing the dealer to agree that they're poor quality/faulty or they have been installed incorrectly, causing premature wear. Hell, my XE-S gets driven very enthusiastically and is still on original discs and pads all round with plenty of life left at 25k miles, 3 years old.

I bought my Approved Used XE when it was 25 months old and the dealership gave it the 2 year service as part of the deal. When I was picking it up, the salesmen told me that they'd replaced the rear discs as part of that service. I didn't give it much thought at the time, but since it had only done about 11K, that is extraordinarily low mileage. I'm beginning to wonder if there was indeed a batch of dodgy discs that are just starting to display problems?

We have seen some terrible deep and pitted corrosion on some cars across the whole disc.
Hard to see how it could happen if the pads are sweeping the whole face of the disc.
A common theme was often used vehicles that had been sitting around a while.

The photos of UV Blue's corrosion shows a band on the outer part of the disc.
Again, the pads should keep this clear as is on mine, so it seems to me we also can have issues with the pads not being in proper contact with a part of the disc.
My first XE (2015) , had the larger front discs and those had been coated in the vanes and on the outer edge of the disc and again no issues.
It would be interesting to know if anybody with with the standard discs has got the coating as well.

A number of causes at play here I suspect:

Lack of use. If your car is not used pretty much daily, corrosion builds up on the disks as they rust continually, faster in wet conditions. If this layer gets too thick, when you do drive the car, unless you do some very intense braking, you will end up with a glazed layer on the discs that can take some time to wear off. If you don't fully wear it off, it can set up further glazing next time you scrub a rust layer off, potentially leading to premature / uneven pad wear or scoring of the disks.

Seized or sticky slides. If your car is not used much, or if you are very light on the brakes, slides don't get to do much. Combine this with pressure washing the calipers, you could end up with sticky slides leading to uneven pad pressure or contact and the resulting non cleared areas of the disks.

Over corrosion prone disks. Some disks rust faster than others. I've got a 19 plate FPace outside at the moment and the rear disks are already looking a bit scored.

Defective pads leading to disk scoring.

My XE-S gets used at least once a week, but is not my daily drive. The disks have taken on a slight blue layer as I've not found an opportunity to drive long and hard enough to clear the surfaces back to bright metal yet.

Brakes International will do a set of front and rear disks for around £180. I've used their Apec supplied disks on track cars with no issues, so they are up to the job for road use I would imagine.

I had all 4 discs replaced under warranty.
Because I am anal I took the calipers off to check the pins were lubricated.

Glad I did as no evidence of any grease.

It may be because Jag say the pin is stainless in a rubber sleeve so doesnt need any lubrication.

I dont really agree so used some Molykote G3407 to lube them up!!

They also used copious ammounts of copper grease which is a rather dated product and looked messy so cleaned that up to.

Brakes are superb now they have bedded in. :)

Good, I hope they come to their senses.

..well they didn't - the dealer just came back to me having looked at the discs/pads and decided they aren't covered under warranty,

the official line on the vehicle health check as follows:

FRONT:
DIAGNOSIS AND TESTING SECTION OF BRAKES ON WORKSHOP MANUAL SHOW IMAGES OF BRAKES AND THE ACCEPTABLE LIMITS/CORROSION AMOUNTS THEY FALL WITHIN AN ACCEPTABLE AMOUNT AND ARE NOT COVERED BY WARRANTY - PRINT OUTS IN JOB PACK SURFACE AREA - 75MM (ALLOWED CORROSION IS UP TO 22.5MM) CORRODED AREA IS CURRENTLY - 15MM (20%) NOT COVERED UNDER WARRANTY

REAR:
DIAGNOSIS AND TESTING SECTION OF BRAKES ON WORKSHOP MANUAL SHOW IMAGES OF BRAKES AND THE ACCEPTABLE LIMITS/CORROSION AMOUNTS THEY FALL WITHIN AN ACCEPTABLE AMOUNT AND ARE NOT COVERED BY WARRANTY - PRINT OUTS IN JOB PACK SURFACE AREA - 55MM (ALLOWED CORROSION IS UP TO 16.5MM) CORRODED ARE IS CURRENTLY - 13MM (23.6%) NOT COVERED BY WARRANTY

they then Quoted for new:
Fronts £813.90
Rear £611.57

I'm pretty fed up about this - I tried to explain that the brakes in use have little bite to them, being quite 'soft' - maybe because less surface area is in contact with the pads when all added up...? - all in contrast to the loaner XE they gave me (basic diesel) the brakes on that are great! :roll:

Dunno, you'd think on a performance car the brake performance would be a big deal and done right.

They recommended if I want to take it further I go back to the dealer I bought the car from - a 330 mile round trip! Groan!

Not sure what to do next... any ideas folks?

:x :evil:

Don't those rust spots wear off when the car is driven?
Mine look like that if I leave the car standing out in the rain, but as soon as I use the car, the rust spots are worn off again.

...yes but the pads are giving uneven wear across the face of the disc so there are peaks and troughs which show up rust more than normal, PeteMcK is right - the perimeter 'rot' is a constant feature however.

ps my car has done 14.5k miles

Said it before but seriously £1400 odd to replace brake discs/pads, someone is deluded! As has been suggested by ChrisGB parts can be had for under £200 and I'd be pretty certain an indie would fit for about the same again saving circa £1000. Alternatively get the discs re-surfaced by Pro-Cut and with new pads I would think you'd be looking at less than £300.

As for staying OEM why would/should you given the evidence.

Those just look like water spots and in the first picture it can be seen that the brake pad has cleared a small section of disc where the car has been moved. This does not however please me as my own modern cars discs all seem to rust like mad but my mk2 jaguar of 1962 never shows any sign of rust when they get wet. It seems that brake discs are now made of a "softer " metal to improve brake pad grip, but as you say if the car is left outside for ,say,going on holiday, we experience the poorer braking whilst they bed themselves in again.

The outer rust looks slightly wider than I would have expected and you have the larger pads and discs. Maybe that is how they wear. The price quoted is a complete farce and I have noticed on building a new XE that many extras have increased by as much as 25%. I suspect the parts are EU sourced and the £ against the E is poor at the moment and may have some influence. The fact that car sales are generally down may make parts more expensive to balance the books somewhat. Have a look at the mudflaps prices on new build and you will see what I mean. They were £89 for a set of fronts now they are well over the £100 mark. (from memory £145)

I had a look at the used XE`s on the Jag website. Two cars for sale chosen at random. Most looked similar to these two. Strange how they always show a picture of the wheels that have horrid rusty discs. Looks like the calipers have been attacked with an acid wheel cleaner to. :eek:

I wouldn`t buy a car with discs like that, saying that I did but they replaced them under warranty :oops:

If your car is still under warranty or perhaps part of a PCP/PCH then you may well need to stay OEM.
I sourced OEM discs and pads for mine for £240.

Agreed though, they aren't of great quality.
