View Full Version : MOT Failed!

Had my MOT today and it failed because of my rear brake pads. The front pad on the rear caliper was fine but the rear pad had almost worn down to the metal which is why it failed. So i bought some new pads and went to fit them only to find that the front piston has siezed which is why the front pad hadnt worn down much.

Ive taken the caliper off and tried to get it loose but have had no luck. Tomorrow im going to take the caliper to a garage and have them blow it out. However if i can find another caliper cheap i might just go with that. Looks like i wont be getting a free retest as this will probably take longer than 1 day to sort out.

I also got an advisory for an overly tight chain. My chain was adjusted by the mechanic at M&S motorcycles when i had my new tyres fitted and apparently alot of the bikes that come out of thier after having the chain adjusted are too tight. Might be why my gears had gotten clunky and stiff.

If anyone knows of any cheap rear calipers please let me know.

Im in a bit of a rush. Im hoping I can get it sorted before its too late tomorrow which is why I have posted this thread before I go searching through all the other threads for possible answers. Quite frustrated now, but glad I found out about my siezed piston before some bad happened. My own fault for not checking both pads.

Don't you get 10 days to fix stuff and get a free retest??

Mate get a refurbed one from Husky alot easier.

Who did the MOT?
Never trust a tyre fitter with a chain. They did one of mine and it had 50mm of play but it depends which guy does it.

is the piston that is siezed the one where the banjo bolt goes. If so M6 50MM and a hammer that how I stripped two rears

Yeah its the side with the Banjo bolt. ill give that a try tomorrow and see what the seals look like. Hopefully it just needs a clean.

Its 10 days for a partial retest but Ive only got till tomorrow evening for it to be free.

My caliper looks in real good condition, no corrosion or anything, just the pistons were a little dirty.

Can you not re-attach the caliper and pump the stuck piston out?

i always thought it was 10 days to have the failed bits re-tested for free?? i would check that out mate cos 1 day doesn't really give you much chance and i suspect they may have been trying to diddle you into getting them to do it for the free re-test. i may be wrong though.

I've got an mot failure sheet and it says
"If this vehicle is removed from the testing station for repair and returned for retest within 10 working days, then only a partial retest is needed and a partial retest fee may be charged"

And "working days do not include saturdays, sundays or bank holidays"

If you got a compressor, bleed nipple slackened and shove air up the nipple.

a bit harsh to be charged though in my opinion, and i've certainly never been charged by an MOT station near where i live for a partial retest.

Got it sorted now. Managed to get the piston out but it was covered in really hard stuff so I took it down to BDS and they stripped it, cleaned it and fitted new seals for £45 so now my caliper is as good as new.

Got my new pads in just need to buy the right size crush washers for the banjo bolt as it was leaking fluid after tightening it. Havent bled the system yet, just flushed it through and the left over fluid was leaking from around the Banjo bolt. Anyone know what size washers the Banjo bolt uses? Going to go Halfords tomorrow and use my old washers as comparison but if anyone knows the size I can order them online tonight. Thanks.

I don't think I've been charged for a partial retest either, I suppose it depends what needs retesting though.
My SV failed on a sticky rear caliperna few years ago and I took it back for a retest 4 weeks later (caught a viral infection which laid me up for a couple of weeks) and they still only did a partial retest and didn't charge me.

A stealer did the daughter for her car MOT, failed because of a dent on the wheel rim. He wanted to fit a new wheel. I said no, I would repair it myself and return it for retest. They refused to do the retest if I removed it from the premises and then tried to scare the daughter by requiring her to sign a disclaimer that she was removing a "dangerous" vehicle against their advise.

3 wallops with a big hammer and dent in rim repaired, off to local station where it flew through. pain was we had to pay twice for the MOT.

I dont take my car anywhere that will not let me remove it to do the work myself....

The only thing wrong with my bike was the rear pad was really low, almost down to the metal. My own fault for not checking both rear pads but now I know why only 1 pad had worn away. Just need some DOT4 and crush washers for the Banjo bolt.

The mechanic thought all it needed was new pads, not a rebuild, so hopefully when I tell him what was wrong he may retest for free considering all he has to do is check my rear pads as everything else passed.

My eldest daughter gets her own cars MOTd local to me in Bedford, even though she's lived in either London, Leicester or Warwick. She took her first car to a garage I know very well when she was 17 and walked up to the counter and said "I'm Laurie's daughter, he told me to bring my car to you for the MOT and for you to call him if it has any problems". They've never tried to rip her off or bull5hit her about anything cos they know I'll be down there like a shot wanting to know what the problem is. She's had cars fail, but it's always been for genuine reasons and they've done the work at a decent price.

Doesn't happen much since she got a company car and only buys the odd toy four-wheeler to play with, which happens to be a 1992 Discovery for playing off-road at the mo.
