The bolts will go with a crack due to the tightness of it being fastened and a little corrosion around the head. No need for thread lock due to the force used to tighten it up. It won't come undone, I assure you.

I bought 2 discs for just over £50 and set of pads, which includes spring clips and bolts, for £30. These were from PCS.

The parts are not covered under warranty as they are classed as wear and tear parts. I enquired, and that's when I got a quote too, of £330.
Doing the job yourself should not affect the warranty, unless you do a bad job and ends up causing damage to parts that are covered. It is maintenance. Servicing work should be done at the dealer or authorised garage though.

When/if you do the job make sure the car is sat on stands or something solid. Don't work on it with it just sat on the jack.
After you have completed each side pump the brake pedal slowly down and slowly up. There will be no resistance for the first few pumps. Stop pumping only when you feel the pedal is solid again and feels back to normal. Don't forget to replace the cap on the oil reservoir if you removed it.

The M14 carrier bolt torque is 90Nm + 90 degrees according to Elsawin

 

Now have my new discs from Rainworth at £64 inc free posting. Pads are also VW/Skoda sealed in box but a tenner from ebay; leftovers from a job never undertaken.

 

Only missing the slider kits which are on back order; Rainworth say they have never replaced a rear  slider kit on a Yeti and were surprised at the issues I'm having with them jamming up.

 

Will probably replace the discs and pads anyway and do the sliders later, as there working at the moment with the rubber sleeve removed and fresh grease.

Mine were ok and not jammed up. The grease was fine and not all hard like you found yours. But I'll keep my eye on it from now on.

That's reassuring, I'm going to watch mine closely when it arrives. Be interesting to find out how many people have had problems.

Managed to change the discs and pads yesterday; pics to follow maybe tomorrow. Anyway managed to 'borrow' a workshop lift which helped and a little bit of advice from my mate who owns his own mobile vehicle service/repair business.

 

He was surprised how bad the rear brake condition had become, after he helped me strip and clean them first time round in the spring of 2012, when the issue first came to notice. He agreed the sliders are just not working properly, after pulling one of the carriers off and finding the pins were not moving again. Hoping the new slider kits due shortly will resolve this issue.

 

Other thing I noted was the level of corrosion on the wheel bearings (housing) the disc mounts on too; had to clean off a lot of loose rust flakes before putting it back together. Inside the back of the disc was no better either.

Put a guide to the rear disc replacement in the Tech section;

BRILLIANT !!!   

 

Thanks for taking the effort Tim. A superb guide as always. I have already saved it as a PDF in case I should ever need it........................Tony

 

No problem, will be posting one on replacing the slider kit when they hopefully turn up next week. Seems this is the main issue causing the failure of the discs and pads.

 

Note the delamination of the nearside disc (to the left in photo) and heavy wear to the corresponding pad in comparison to the outer face pad. Offside pads are similar but with slightly less inner wear. Think from the evidence the calliper has jammed up in the engaged position giving the piston little room to move the inner pad away from the disc face, leading to overheating and the grooving of the pad and disc. The outer pad has stayed almost static thus allowing the disc face to corrode away.

 

 

Anyway I'm hoping the new sliders will fix it, if not carriers; although in truth this should be warranty but try get Skoda to admit there is a fault; local dealer, when I first noticed a problem in early 2012, stated sticking brakes not a warranty item

Hi Tim - A pretty poor response to your complaint by the dealer! Fortunately our local dealer (Simpsons Škoda) is MUCH more sympathetic and pro-active in rectifying any defects. 

 

I think I would try sending a copy of the pictures, together with a complaint detailing the dealers response to ŠUK. Ask them to comment and request that they meet the cost of the parts - it's worth a try! The pictures speak for themselves. It certainly should have been dealt with as a warranty item................Tony

 

PS This thread made me double check our SM. The disks and pads look just as they did when it was first delivered [sept 2010]. Shiny bright with no scoring of the surface. Nothing like the extreme wear that you have! But all this will ensure that I keep an eye on them! Thanks again............T

TIm, thanks very much for the detailed guide.

 

I had another look at my brakes today.  The nearside looks OK, but the offside disc is pitted from about 1.5cm away from the outer edge, to the outer edge.  Something seems to be stopping the pad from contacting that outer part of the disc.  I've not been able to look at or feel the inside faces of the discs, there's a cover in the way.

 

On the other hand, the swishing noise I had noticed before seems to have gone away.

 

I think I'll leave this for now, bring it up at the next service (less than 2,000 miles to go) and see what the West End folk say.

I've just been quoted £226 to replace both rear discs and pads.  Given that I priced the parts up at £133, I have to decide whether a saving of £93 is worth the time and effort I'd spend doing it myself.  Could be a close call.

 

The other consideration, though, is whether it would actually fix the problem.  If sticking sliders are the cause of the scoring, then unless they service the sliders as well, I'll just be looking at another £200+ bill in another three years' time.

 

Hmm...

£133 is still £50 more than I paid. Try a local car spares and not a main dealer. I used PCS but unfortunately its not a national business.

In my case the sliders were still ok. The grease was still......err.....greasy, not dried and gunked up. The sliders were still in good condition and they were working correctly. 

 

Those discs in Plumbers link above look a bit strange to me. They are painted all over, including the braking surface. I've not seen new ones like this before (not as though I've seen many though). Do some come fully painted? Also look at the groove in the front face. There's some lumps and bumps in there. Could this be corrosion having been sprayed over. Is it possible these are reconditioned! Look back at my pics of new discs and the grooves look as machined. But I may be wrong.

 

Maybe I should skim my old ones up at work and spray 'em up, they would still be in tolerance!!

They're not painted, they look the same colour as the ones I got for our Leon last week.

They are as supplied by VAG; got mine from a main dealer and they where identical to those in the picture. The paint is just a light protective coating and strips/burns off after a very short test run and application of the brakes.

Thanks for those links.  The prices I had were from online vendors - including eBay IIRC - but yours are cheaper.

 

I'm currently thinking that I'll leave it until after the winter when (a) I will hopefully have warmer weather to get the job done, if I decide to do it myself, and ( my brand new discs won't immediately get coated in road salt(!)  I've not noticed any adverse braking behaviour and the car's passed its MOT so I'm tempted to treat the issue as non-urgent for the present.
