Pulsating brake pedal/AP 4 pot discs and pads.

[cab260175]

Hi

I can feel the brake pedal pulsating when I brake very lightly (usually in traffic). I think that I have a warped disc that is knocking the pads back hence the pulsating. Under medium/heavy braking it is fine. I have taken the front wheels off and turned the hub by hand and the front right catches as you turn it. Is this a 'standard' characteristic of the uprated front brake kit?

I intend to change the front discs and pads, what make of pads do Caterham supply as standard and can anyone recommend any alternatives such as Mintex M1144?

Thanks

Well, discs off and skimmed (£28/disc), new Mintex M1144 pads and a change of brake fluid. The pulsating in the brake pedal has gone and it stops smoothly from low speeds.

If anyone else intends to do this, ask to have the discs ground rather than turned/faced on a lathe as this takes off less material. The machinist that did mine said that the discs were only slightly out. Having it done has made a huge difference.

If you need to change the discs ask one of the independant specialists that advertise in the Lotus 7 Club's Low Flying magazine as they can supply discs cheaper than Caterham.

I think you mean 'Turning' not 'Lathing'. According to the ex Rolls Royce machinist that I use surface grinding takes off less material.

Not intended to be a handbag Incorrigible, only useful information. Now you can walk into a machine-shop, have the minimum amount of material removed from your discs and avoid the embarrassment of being corrected.
