Help with car brake discs

Hi, wondering if anyone on here has any experience with car brake discs?

I have a Honda S2000, and had the car serviced on 18thDec, where I was advised by Honda dealer that my rear brakes had approx 30% life left, knowing my Mot was due last week I left them til then to do, as my mileage is very low at the mo, it failed on one rear brake disc, which is pitted and corroded? Would they have been able to see this when they took the wheels off at the service to swap round and check the brake pad levels?
I've only done 170 miles since the service, and find it a bit strange, but I'm no expert, so hoping might be someone on here would know.
It was a very comprehensive major service I had done
Thanks in advance for any help

30% of life is an approximation given the thickness of the discs or pads remaining (you don't state which you were given this number for, most probably the pads only). They would have been able to see it if it was there, but given you do so few miles it could easily have been caused in the last 2 months.

Do you think it's worth getting a 2nd opinion from another garage? They've quoted £275 + vat for 1 disc fitted, also need 2 new rear tyres, though only been on 7 months and done 3000 miles ( couldn't fit behind wheel when I got too pregnant lol ) just feel that maybe cos I'm a woman they are taking the mick a bit??

You can't just replace one disc, you would normally replace both discs and all new pads. Unfortunately a car left unused is susceptible to pitted discs.

Tyres are easy to check yourself.

But it's down to the examiner to decide if a disc fails or not, could of been they failed it for the job of replacing like most MOT places do
Take it to a council MOT testing station next time, they only do MOT's so nothing to gain by failing


grrrrr :x [SIZE="3"]ALL [/SIZE] testing stations have to conduct the same test procedures wether they test/repair or just carry out test's.

god that gets my goat everytime someone posts that about testing stations !!!!

Of course the reality, as most of us know, is quite different.

Many fail borderline items in order to get work.

So your saying if a 1000 testers looked at a car with 10 set minor faults they will identify everyone one of those faults with matching results and weather it fails the MOT LOL :w00t:


that fact im not disputing as i know myself i have passed/failed vehicles after another tester has tested it, but what i am disputing is you seem to think council run mot test centres do something different.

btw as you possibly are aware if your not happy with a test, pass or fail, you can appeal, just to make it even eaiser you print an appeal form off online. VT17 appeal form

They do, they do not have an agenda to fail borderline cases to get work.

They are completely impartial.

It is time VOSA stopped MOT Stations doing repairs, on their own fails.

Isn't the cost of appealing the same as a MOT lol


The cost is refunded if the appeal is successful.

boderline cases should be a pass & advise, I'm impartial, i dont get a car in thinking oh good we need some work today, what can i fail it on. I test a vehicle as presented I dont magic up failures, I grant you there are testing stations out there & that includes council run ones that do.

whatsThePoint;7898268
and what if they find something different to fail it on

Then don't appeal, it's clearly only worth doing if you're confident the car should have passed when it didn't.

So you agree with what we are saying :roll:
But how wide is a borderline?
its hard to show borderline examples on here, I'm not sure if you do, but next time watch a test being carried, you can see whats involved, its not a quick kick of the tyres or just a light check.

And how can a council one fail a car to make some work for themselfs


they have headlamp beam-setters, not may garages that dont do MOT's dont have access to them,so it would be down to the testing station to adjust the aims & then charge, our local ford dealership charges £10 to adjust headlamps, we charge nothing !
#12
hijack the thread why dont you:roll:
#13
whatsThePoint;7898393
so your saying every possible part that can wear/corrode and cause a fail should be replaced for a MOT :whistling:

No, not at all - I've no idea how on earth you've jumped to that conclusion as it has nothing to do with my original comment. If I had a car in good condition that passed all the requirements for an MOT but had failed on a defect it shouldn't have then I'd ensure before appealing that the tester was definitely at fault and the car should have passed before appealing it. Clearly it would be daft to waste time/money appealing if the car is not in a condition to pass an MOT.

Exactly my point, only council run ones have nothing to gain, so it doesn't happen with them.

No worries, it's all made very interesting reading, thanks for the help/advice, will pop it along to another garage just to check ( will get oh to take it ), and if def needed will have a scout about to try and get one cheaper and see if oh can fit it, didn't realise they have to be done in pairs, the quote def is just for 1 disc on o/s/r :?

What did they say was wrong with the tyres? I had a car that had the front tyres misaligned (both pointing outwards slightly) which meant I had to scrap a tyre with 8mm tread because it was visibly damaged due to the misalignment along its inner edge. If the tread level is generally too low you can double check this yourself quite easily although I wouldn't have thought this to be the case unless you're using soft tyres and have a heavy right foot.

Pitting can occur on brake discs when the car is not being used so that is possible from what you've said. Given you're facing a pretty big bill if there's another garage you know can be trusted I wouldn't hesitate to get them to check the car. I tend to find National Tyres are pretty honest about tyres/brakes although that may vary from region to region. Kwik-Fit (didn't go there by choice) were very keen to replace my front tyres and brakes which had been on for less than six months and had no visible issues - another mechanic found no problems with the tyres or brakes.

richp - I do agree with your points, I take my car to a mechanic for its MOTs and can't fault him. If I don't trust them to MOT the car then I definitely wouldn't trust them to make any repairs to the car either.

They've said 1.6mm across the tread on both tyres, have bridgestones w rating as recommended by honda as its classed as a performance car, think it maybe time for it to go, hubby been nagging at me for ages to get rid and buy a more family orientated car:x

Your words "confident it should pass"
As any MOT tester can fail any part of a car they feel has worn/corroded enought in their opinion not to pass, replacement is the only option for a person to be 100% confident as you suggest


Absolutely not, there has to be consistency in the MOT process which is why there is an appeal system in place - testers cannot fail cars that others are passing. Corrosion simply isn't that subjective, for the car to fail its MOT on this issue the corrosion has to be excessive - again, if your car is marginal then it's probably not going to be worth appealing however it can be easily possible for there to be mild corrosion that shouldn't have caused the car to fail.

Even allowing for the car being a reasonably powerful rear wheel drive car, that seems to be excessive tyrewear as you don't sound like someone who is doing burnouts all the time. Have you checked the tread yourself? Did the garage give any reason why they thought they tyres had worn that much?

Only visually tread seems quite deep to me, garage just said fair wear and tear, I pointed out they only fitted them 3000 miles ago, and service manager said must be my driving, but as I was pregnant until mid Oct, then hardly drove it, I'm not sure, and I'm not exactly a boy racer lol
#22
Con and Use Regs state that tyres must have 1.6mm of tread over 80% of the width of the tyre and throughout the whole circumference. For MOT purposes, there must not be less than 1.6mm in the central area of the tyre.
So if the 20% at either edge is missing the tyre must still pass unless there are any other flaws which would cause it's failure. In this condition, I would expect an advisory notice to be issued.

Take a photograph of the tyres for us to help you judge?

I don't know of anybody that would replace a single disc on an axle and it is almost always correct to replace the pads if you are replacing the discs, otherwise the pads will cause strange wear.

I would def get a 2nd opinion on the tyres as 3000 miles is ridiculously low for a rear tyre - I drive a 1.9 turbo diesel with 130bhp and my car is driven 10 hours a day 6 days a week by learners - and my rears still manage 20000 miles, although the fronts do only survive about 12000 ! Ah the joys of front wheel drive lol :thumbsup:

The S2000 is a RWD car, so that changes the wear to the front, although it is still front engined so the mass is still at the front. Your learners will be very soft on tyres and a typical 130 bhp diesel against a 240 bhp S2000 is slightly different :thumbsup:

However, I agree that 3,000 is too low, but it depends on how the car is driven and is not beyond belief. A photograph would sort this out.

The mystery of the tyres has been solved, when I had the car serviced the tyres were swapped around, not just from side to side, but front to rear, unfortunately the tyres on the front and rear of a s2000 are different sizes, I didn't spot it, cos didn't think to check! this was picked up by the garage I took car to on Sat for 2nd opinion, luckily the garage where car was serviced had notes wriiten on file by an apprentice to say he'd swapped tyres front to back etc, so am getting them replaced for free, the price quoted was for a pair of discs although it said just 1 on the qoute and because of the hassle with tyres etc, they are supplying labour for free, so I'm happy with that, thanks for all the help!
