Brakes - more problems
Brakes - more problems
21-09-2016, 02:12 AM
Anyway, following that, for about 5 mins after that I had horrendous judder every time I even gently touched the brakes. After that it went back the mild judder I've been suffering for a while.
Does that help in any way diagnose what the problem might be? (Going to ask Tony the same question before getting it booked in, but just don't have time to take it up there for the next few weeks)

Sorry to revive this old thread again, but had a new thing occur this morning. Had to jump on the brakes really hard when some idiot tried to run me off the road (commuting at rush hour is proving to be quite dangerous, need to be on the ball so much more than at other times).

IS200 Turbo project now just about complete ! See my thread here and leave your comments.
Now running standalone Syvecs ECU and no stock ECU !

21-09-2016, 10:44 AM #22I still think it's something to do with being an auto, and holding your foot on the brakes when the car is at the traffic lights etc. If there was a lot of juddering which then reduced somewhat that makes it sound like a build-up of material on the discs which then was partly cleaned off again by further braking.

So is that normal then from heavy braking? Get brake material over the discs, which causes vibration until it's cleaned off?

parthiban So is that normal then from heavy braking? Get brake material over the discs, which causes vibration until it's cleaned off?I don't think it's normal, no. But perhaps there's a bit of a problem with your brake discs anyway, e.g. deposit build-up from the pads, which got worse when you did heavy braking (incompatibility between your discs and pads ?).
According to articles like this one, most cases of "warped" discs on road cars are down to build-up of such material rather than real warping (don't know if that's true or not, but sounds interesting).

I went against my own normal rule about going non-OEM for brakes, but they're mintex pads with adl blueprint discs which I think many others are using without problems?
Either way just going to try to ignore it until I can get Tony to check it out.

I have no problems like described however and the discs/pads on mine are about 2 years old.
Personally i usually put mine in neutral and handbrake when held at lights and queues anyhow?

22-09-2016, 12:56 PM #26There is a tendency to get extra build up on discs being an auto as Steve said, and i think in extreme circumstances if the discs are hot then they may warp being held on them, but v unlkely i would have thought!!

IS 200 Sport with a few mods, Standardish IS-F. The IS250 SE-L with a few mods has gone to a new home.[SIGPIC][/SIGPIC]
I absolutely agree with that article, as in all my years of driving, including track and hillclimbing, I've yet to see a 'warped' disc. Plenty of cracked and scored discs, but 'warped'? Never.

In some ways yes, because the judder at low speeds is now gone :thumbup:
However, the judder under high speed braking is still alive and well and no better. I'm going to have to take the car back to them now to dig a bit deeper but they're thinking that it's probably the flanges.........and this could cost over £1k to rectify

As per my other thread, had the car in at WIM over the weekend, and more bad news unfortunately. They checked the brakes over, and found that the sliders were sticking. So they sorted that and we hoped that was the problem sorted.

What flanges are those ?

Not sure to be completely honest, didn't get into too much detail as we're not sure if that is in fact the problem until they test for it. I believe it's something that sits behind the brake disc as they said a small deviation in that is what causes the vibration.
But basically they said if the flanges need replacing then the bearings will also need replacing, as will the brake discs and pads and that's how the bill gets so high.
