Brakes shuddering and rear disc seizes
« on: November 13, 2023, 03:31:13 »
Have any of you experienced this?

The rear brake pedal has a shuddering sensation, like the pads are vibrating on the discs and they do not grip.

After riding a while the rear disc also almost seizes up - the caliper is extremely hot and the pads then seize on the disc.

I posted earlier about unlinking the DCBS and I think I have to now because it's dangerous.
VFRBoy because I had a 1998 VFR800Fi for 8 years

Now I have:
1999 XL1000V Varadero
2000 XR250R
1989 GB250 Clubman

Sorry, I don't remember reading anything like that before.
It looks like it has nothing to do with any Varadero or CombinedBrakeSystem known problem.
So, my guess is that you are suffering from some quite general problem, unrelated to Varadero-CBS. My knowledge in mechanics is so poor that I can provide no useful clue. Sorry.

Good luck!

As Josep, never seen something like this ... have you changed the pads recently ? surely have to lubricate the pistons ... is it when you only use the pedal (externals pistons) or both with front brake too ?

I do not ride fast, I ride far / I'm not lost, I'm just exploring

Would suspect that the rear brake activation from the front disc set up is sticking on causing the rear brake
to be on all of the time. Possibly the rear disc has warped causing it to pulse on activation.
Suggest all three calipers need cleaning and checking fully.
Good luck
