Front & rear brake discs

Post by philkinnaird » Mon Feb 19, 2018 3:28 pm

Just had car serviced and advised replacing front and rear disc due to wear and corrosion.
Mileage is just over 24k. Rear discs were replaced last year under warranty and advised better quality discs would be fitted. Appears problem still relevant
Any one any info on front disk wear or is this normal at 24k.
Price quoted for front discs and pads £566. Is this normal price for this work
Would appreciate any feedback

I would normally expect a set of discs to last more than 24k; discs normally are replaced if they are less than the minimum 'safe' thickness, severely pitted or corroded. I had front discs on a Jeep Cherokee replaced at 30k but they were known for this, I think that cost me about £800 from the dealer. Discs on other cars I have owned have lasted a lot longer & I have always shopped around online for a good make like EBC. It will be interesting to see what other DS owners think. :D

Can't comment on the DS discs as mine has only done 12k - but they do squeal fist thing in the morning.
The FL2 auto that I ran for 185k miles used rear pads every 20K and front pads every 60k. Front discs lasted 120k, and rear discs/drum/shoes lasted 100k miles. It's a similar weight car, from the same manufacturer, driven hard - hard acceleration and late braking rather than speeding.

So I would expect similar performance from the DS
2018 DS HSE Lux.
2017 DS HSE auto, for 45k nice (grey!) car.
2014 Ewok for 6 months, really really rubbish.
2008 FL2 for 185k miles, should have kept her.
2006 FL1 for 110k miles, brilliant car.
2000 FL1 for 100k miles, fell apart but started the LR bug

Brake disks are often changed unnecessarily in my view, its a nice little earner for tyre specialists and MOT test centres. Grooved disks stop just as well, maybe better, than perfect ones so unless they are weakened to below the minimum thickness, which is in itself a conservative estimate, I would resist changing them. Pad life may be slightly reduced but new pads bed into worn disks very quickly and with no loss of efficiency. The exception might be for towing in exceptionally hilly or mountainous areas.

Andy, there is a 'fix' for the brake squeal in the form of new type pads, I had mine changed under warranty at the dealers & all fine now. :D

Modern brake pads are more abrasive than the good old (depending on your opinion) asbestos pads. Asbestos was a great material for brake pads, it just wasn't particularly healthy... You never got the squeal / graunching problems you get with modern pads either, so now calipers and pad carriers have odd lumps of metal on them to tune out the squeal.

Modern pads cause thickness variation of the disc (which you feel as judder), it's created when you stop with your foot on the brake after a high energy stop so the disc can warp as the pad heat transfer isn't as good, or from off brake wear on a motorway (pads sometimes not fully retracting and lightly touching the disk).

So the pads are now used to effectively machine the disc smooth again, which wears the disc out way quicker than years ago so they need replacing at what seems stupidly low mileages.

I have had my DS at the dealers for brake grinding sound. They now tell me that there is corrosion on the front discs and this is causing the pads to wear down. I have only covered 31,000 miles which has certainly not been hard driving.
How long should discs and pads last?
The dealer want £500 for the work. WTF!

Brembo front discs and pads are currently £168 from EuroCar Parts, after applying their discount code - i dare say cheaper options in terms of brands are available from other motor factors.

Dealer probably charging 1.5 to 2.0 hours labour so there's £250 or so of the cost.

Brake life dependent upon use, driving style, location (salt water etc) - just changed the original brakes on my other car after 15 years and 51k miles, discs at their minimum thickness, pads half worn.

I have just been on Euro Car parts site and can get a 45% discount on my first order. I have already had the rear discs and pads changed under warranty at 21,000 miles.
I am being charged £66 for checking the car!

I don't know how old your vehicle is, but if >3 years, please see attached document offering fixed price discs and pads at £375 inc.
