UK S2000 Disk Brakes Rotten!

hatters · 06-02-2005, 01:07 PM

hey people,

new to this site, so be gentle

I have just got myself a Jan 2002 Rev2, I thought it best to go to a garage rather than private due to my absolute ignorance in mechanics!

however, since gettin it home, a few people have told me that the rear disks need urgent attention, and fair enough, they do look in a mess!

On both the rear disks it looks like there is no contact on the outta inch or so with the pads, so the disks have rotted! but seems a little odd that it has very recently had new pads and passed an MOT and had a service. I dont understand.

am tempted to go back to the garage and have words! but wanted to check this is not an S2000 problem of any kind? and i live some distance from the garage.

any advice at this stage would be great,

cheers

hey
it is very normal that for s2000 the brake disks has some rotten areas on the outer edge where the pads has no contact with the disk. however in your case it seems to me that you are talking about the part of the disk where it should have contact withthe brake pad, then thats abnormal. in general the very outer edge of the disk will corrot on most s2000 ... don ask me why i dunno to, but mercedes never has this problem ... @@

I can see your avatar seems to be a pic of the rotor/pad interface but it's a bit small to tell exactly what you mean.

I looked at mine and there is full contact between the pad and rotor. I'm not sure what you mean by 'rotting' but pads are not made of materials that 'rot' in the strictest sense. The rotors can warp, of course, and cause a gap like you describe but this is uncommon in the high quality setup we have on the S (save for cars that see a bunch of track use on the stock brakes) and even less so on the REAR brakes even in a car that's tracked.

I'd definitely head back to the shop that services your car and have them inspect those brakes. When it comes to brakes and steering I don't like to mess around. Drivetrain problems can leave you stranded, brake problems can leave you far worse off.

Halo,

Thanks for your reply.

yeh the avatar is a pic of the rear disk, you should be able to see that half the disk is in "silver" (hahaa, showing my knowledge here) and half has gone a "rust colour" is kinda bumpy and rough.

oh ok, i just read my paragraph above and i really should be giving up here.

however, i phoned the guy from the garage and he gave me all the usual rubbish about passing service and mot etc, and that if i take it back he will get someone to have a look. but the garage i got the car from is over 2 hours drive, and i am kinda short on life hours right now.

maybe i should just take it to my local honda dealer? but i can guess exactly what they are gonna say "new disks" needed or not. hmmmm.

erm, yeh, so would it help to see some more pictures of this problem or does 2D just not cut it?

hatters

BTW. to anyone reading this and thinking of buying an S2000, i love my new car and would not have got anything else, it rocks. i am just a bit of a clown when it comes to mechanics. sorry

If thats what your disk looks like after a heavy drive then something is seriously wrong.. rotors are warped and need machining or the caliper/pad is installed incorrectly or worn out.. try to get a mechanic to check it out.. going from your picture it looks like a road worthy issue..

estern · 06-03-2005, 05:46 PM

Looks like someone used the wrong rear brake pads. Fortunately disc brakes are easy. Buy some new pads (from Honda). When you pull the old pads pull the rotors and have them turned (machined) at Honda or a shop with a good reputation.
When you install the rotors and new pads refrain from braking hard for the first 200 miles so the pads are properly seated.
The rotors are cast iron and as such are apt to rust. This can be seen on the outside edge. Rust is normal. It can also be seen on the face of the rotor when it gets wet and sits overnight; normal braking cleans the rust off the surface.

Cheers!

wow now i see the pix, when i was posting i didn't know what u mean, now i get it. for the disks you can take it to the shop and use machine to grind it to make it smooth and get rid of the rusts. and yeah the pad is definetely not cool ... u need a better pad.. that will be able to grind the disks better, maybe one of those metallic is better, honda's is kind of rip off.

Hey Hatters;
Don't go puttin' yourself down because of your lack of mechanical knowledge. You don't hafta be a mechanic to enjoy an S2. All you gotta be is a driver.
I'm findin' that you're gonna find some knowledgeable experts on this site and you're gonna find some real dweebs that know some of the buzz-words n', unfortuneately, have access to the internet.
(You can usually spot 'em by the testosterone surges that affects their ability to type n' their squeaky voices) You seem to be gettin' involved in the mechanical condition of your S2 already. Granted, it's only lightly, but you're obviously not scared of it either.
We're all still learnin'. If we ain't we might as well be worm food.
Good luck and congrats on your new ride. Knowin' the mechanical end of it or not knowin' the mechanical end of it . . it's gonna put a smile on your face.

Keep up the good work java.

Java,

appreciate the support

this site is currently making new friends in my favourites.

hey, just to update.

I dropped into Honda at the wkend for some advise on my disks. was a little slick about it and drove strait into their garage to avoid the daylight robbery know as the front desk

the mechanics there suggested that previous disks were probably at fault, this led to the outer rim having no contact with the pads.

They suggested it is still safe and should pass the average MOT test and service but is not as sharp as it should be, they advised i get some new disks fitted.

My only thought on this was, if the current pads (december04) are not in contact with the whole disk, will they now need replacing?

Honda quoted me ?141 including fitting for the 2 disks i thought that was pretty good?!?

keep up the good work guys,

Hatters

Total truth in Halo's warning.
Alotta things can be crappy about a vehicle n' the vehicle can still get you from point A to point B. Brakes n' tires are not included in that group. Brakes n' tires can get your ticket punched.
Similarly, your engine can run like 10 pounds (Im talkin' weight here guys) of ka-ka in a 5 pound bag for alotta different reasons n' it will PROBABLY go on gettin' you from point A to point B. But let anything happen to your oil pump or the oiling system, Voila! Instant paperweight!
Some items are very definitely more important than others n' warrant your attention even when you're neglecting everything else.
