Hi, I haven't had my 300 too long, and I've only been a member on here for a short time so please experienced zeders don't laugh at me.

My problem is a "pulsing" feeling through the brake peddle when braking. I don't know if this is relevent but a couple of months ago I had to top the master cylinder every week for about a month, but there was no sign of a leak anywhere. I originally thought that it was just a case of a worped disc, but now I'm not so sure. BTW I haven't checked the brake pads for wear. Any help/info would be greatly appreciated.

sounds like warped discs to me, maybe youve got a sticky caliper and its heating one side of the disc up more than the other.

its not the ABS kicking in is it? how hard were you braking?

Mickl, it happens all the time regardless of how soft or hard I brake. I've spoken to z world, and there opinion is a worped disc probably at the front.

Sounds like warped discs to me its verry common We skim discs all day long with our on vehicle lathe.

Hi all had the same problem but mine was bad, ive just had new front brake discs and pads fitted today by ztech as discs were warped most of it has gone however still a very small amout there this is due to the rubber tie on way out which shall be getting fixed soon. hope this helps

Warped discs or / and tension rod bushes most probable cause.

warped disks mate, they are shite on the zed.
