Braking vibration

[HumbleJim]

Hi severe judder (was minor but getting worse) medium braking from 70ish a bit through the steering but seems to come through the whole car. All the discs and pads are within tolerance but the rears look like this. Lines radiating from the centre out, is this "pad pickup"?

Thanks, I've ordered the parts.

Knackered discs & pads is what it is mate, all need replacing.

Barely 2/3rds of the surface is "in use" by the swept area of the pads, the rest is VERY badly corroded.

So what would you suggest is the root cause of the corrosion on the disc? (HumbleJim I just posted in your other thread)

Thanks I saw your post. I've had the car for 11 months and covered 4000 miles, the discs never looked too good. Prior to my ownership the car had been doing very few miles (20k in the last 10yrs) so I'm catching up on quite a few things caused by lack of use. The calipers do seem okay though, not sticking and the pads have worn evenly.

I couldn't remove one of the rear pads when I was trying to clean it up the other day, caliper bolts seemed stuck to.

I soaked the caliper bolts with some "loosen up" and they are free now.
I've ordered premium discs/pads/fitting kits from GSF £70 (bargin) I will give it a good clean and a smear of copper slip when fitting.

£130 was for the front vented discs, they look a lot better so I'll see how it goes.

Rear discs & pads fixed it.
The parking brake shoes fell apart when the disc was off so replaced those too.
