The Mégane II Owners' Club

i had new discs and pads put on in November last year and I think they're warping already! Bought Delphi discs and pads from Camberley Auto Factors. Can anyone recommend some better ones?

What makes you think they are starting to warp? Are you getting brake judder when press the pedal?

I always thought Delphi stuff was pretty good

AlexB has posted about discs before, maybe PM him?

What do you mean by "warping"?

as Iain said, there is brake judder when braking and not only that they are very crap, stopping is quite scary at times!

Maybe your pads are contaminated?

i'll get them checked. A mate of mine fitted them for me so will be going back to him and saying 'Oi, was this about!' lol
He'll owe me as I'm doing some old style stickers for his old Chevron race car

"Scary"? As it is not just a noise, but the actual braking is affected, then you should stop driving and investigate the problem. Remove the wheels and calipers first. If the fault is not obvious, then photograph everything and post here.

I've read somewhere, that there was a batch of Meganes with deformed brackets to which the front calipers are attached. These are sold at about £10 on ebay, if I am not mistaken. Do you remember the official Renault fix for squealing front brakes? There might be a relationship between this fix and the deformed brackets. It's just a thought. I am sure that someone like Webcode knows better...

if it's not a manufacturing fault or cheap parts then is it your driving style thats causing this ?
warping can happen if you have hot brakes and you leave your foot on the brake for long periods, i.e. in a queue, at traffic lights etc.
The part of the disk where the pad is connected is hotter that the rest of the disk, so as the rest of the disc cools it warps.
Thats why there is a hand brake

Yep, this is one of the myths in which many drivers believe. In reality the pads are touching the disks even when the brakes are disengaged, so the handbrake makes little difference. It is recommended to use the handbrake because (a) the attention span of an average driver is shorter than the period of waiting at traffic lights and (b) as a driver in the following car may find your stop lights overly bright and be forced to keep a safe distance...

Furthermore, disk temperatures in town are usually not very high, which may create a different problem. In winter the disks may stay wet after you parked the car thus causing corrosion. In super cars there is a system which keeps the disks warm (for a different reason). In cheaper models it is the business of the driver.

If it's not too bad get it machined out.
