rear brakes

Post by ted clutch » Sat Aug 08, 2009 11:54 am

the mot man has just condemned my car. rear service brakes are 48% efficiency. but odd enough the handbrake passed so dont think the calipers are siezed. 't' discs have good amount of wear and so do pads so il be changing em.tester said to remove the pads. they look stuck in the carrier.my question to you is how many types of rear disc are there.i know about hub (no-hub like mine) but listings say turbo,2.0,abs etc.also will 440 discs fit.

On the rear I'm not sure. just check buypartsby.co.uk and cross check part numbers to see what modelos interchange. I think (this is from memory of about 4 years!) there are just hub / no hub normal discs and then vented discs. I imagine yours will be normal discs, no hub. Just make sure that you release the calipers correctly. You remove the 5mm alan key bolt dust cover on the back to reveal a 4mm alan key hole you wind back to slacken the caliper. when re assembling, refit new pads, then wind caliper in until it is tight against the pads and slacken off a couple turns. This can be tricky so for exact adjustment, put the wheel back on and then once tighten the caliper using the 4mm alan key hole then try to turn the wheel while gradually slacking it off. When the wheel starts to turn relatively freely (should be slightly grinding - not difficult to turn but then not spinning really freely) stop and but the dust cover back on. this method will ensure your handbrake stays tight.

Sorry for my terrible grammar, typos and nonsense! Please say if you need anything clarified. In fact check out Stu Chacks guide he did. I think it might be a sticky.

I know this thread is 5 or 6 years old, but did changing the disks and pads get her though the MOT?

I have the same problem right now: Handbrake is fine, rear service brakes are 19% below required efficiency. Changing fluid and bleeding through has helped a bit but not enough. Pads are just 2 years / 4,000 miles old with lots of depth and I checked the calipers when I changed the pads

ATS (where I got my MOT suggest changing the pads, then disks. We had a good chat and I trust their mechanics. Pads I can do easily (but I'd pay a £15 MOT retest fee) whereas I may let ATS handle the disk change as I get 15% off via the RAC (£135 all-in).

Anybody have any suggestions?

Thanks

My car failed on service brake efficiency even though the handbrake worked . The caliper on e side needed to be stripped down and rebuilt problem solved.

Thanks Jim, I think you may be right, but it'd be on both sides.

Chatted with the mechanic who checked the brakes and changed the fluid when I picked up the car today. (Fluid change is an easy job, I know, but £40 for a professional look and all the fluid is worth it compared to buying the fluid myself and buying a new Holts Eezibleed kit). He said both rear brakes are equally under efficiency - i.e. on both sides. Both were pretty shitty and the bleed nozzles were blocked, he said. Although one caliper is original the other is about 8 years old, and I gave them both a good look over last time I changed the pads.

When they changed the fluid they kindly adjusted the handbrake cable and pads. The handbrake is now much looser (i.e. more clicks) than when I took it it - but it passes the required efficiency! Service brakes have risen from 54% to 60% of minimum efficiency (I was wrong before - Handbrake was originally 13% below, service brake was 46% below!).

It's also possible I've somehow managed to glaze the pads, and I think I've got to look into that before I buy a couple of caliper service kits.

For the record, ATS are quoting £195 to change both calipers (though he's offered a 10% discount on parts :D ) and I found a seller of refurb calipers on eBay for £25 (free P&P) after you send in your old ones for cashback.

I'll report back once I've checked the pads.

Jim

was that a service kit , from where?

I'm sure mine will be iffy again, they seems to be free enough with the adjuster winding piston in/out and the brake pedal moves the piston OK, but rear discs get rusty quickly, maybe not harsh enough used, mostly pottling around town :-)

in fact I skimmed them last year in lathe at work and within a month all rusty, even though passed MoT :?

No I left it to the mot garage to fix then remot the car. It was the easiest way to get it through the mot. :D

Tonee made it though the MOT with a bit of a helping hand from my local ATS (who are a brilliant bunch, like a local garage). :hopping:

I had to sand the pads down as they were really glazed and remove some rust from the edges of the disks (yeah - I need new ones), and I cleaned the caliper guide pins so the pads released properly. This allowed me to get the pad and cable adjustment spot on.

Rear service brake efficiency was within limits after that but the nearside handbrake was um "borderline" - yes, she got through but with a "strong advisory" to get a new caliper and to regularly spray the handbrake mechanism with WD 40 in the meantime.

Even though both rear cables are relatively new, the nearside one looks stretched and the caliper (which was supposedly replaced for the previous owner - the garage billed him but clearly did not do the work) is slightly different, meaning the rubber boot on the cable is all mashed up - anybody else found this (the cable thing, not the dodgy garage)?

ta for info, kinda hoped you'd found a source as there seems to various qualities out there :-( , I'll just trawl the net for parts :-)

the cables seems to suffer at the caliper end, (on every one I've fitted) the bellows under the floor are OK, copious volumes of 'sticky' grease seems to help, this is stuff design for slide ways on fork-lift etc :-)

My rear calipers need rebuilt as they will certainly fail an MOT :P I was just wondering if anyone has a guide on how to rebuild them - I saw a few posts on here in other threads as well saying that someone has made a thread but I cannot find it for love nor money.

Thanks.
