Rear Brake Locks Up Too Easily

Hi all,

Discussing this with other Oz 660Z riders and they mainly agree with me. My rear brake seems to lock up without too much effort on my part. This causes me some distinct directional and stability problems when going downhill, on smooth dirt or loose stones and turning corners - all at the same time.

In an emergency (caused mostly by me), it's almost impossible to bring the bike to a stop without locking up the rear, and this happens on bitumen too!

The bike's only done 5000 miles so I would imagine that they are the original brake pads.

Any ideas??

Weight distribution and suspension settings?

Trev, if your brake is that drastic, what I'd do is reduce the pad-to-disc contact area by grinding part of the friction material away from the end (or middle I guess) of each pad. Steady is good here. You don't want a weak brake (mine is for some reason. Probably got silicon spray on it). Also you have to ensure the pads are even.
Another variation I haven't tried is cutting vertical slots in the pad material, again to reduce contact area.
It might pay to have a spare set of pads handy in case of experiment overkill...
I don't know how altered pads react under severe road pressures, so be careful mate. Good in the dirt, though.

Could be, but have had both ends done and so many others over here in Oz are having the same problem. It could be the pads they have here 'cause some say that they have fixed it by replacing them.

Used to do that to car ones to take out the squeal sometimes. Might try that as I have a set from Off The Road sitting in the shed ready to go on.

It's a pain in the backside though because it only happens when I REALLY don't want it to.....:087:

Thanks for your input guys.

That sounds like a good suggestion too, Cheers.

Tyres ?

Too hard, too soft, crappy compound ?

Are the brakes binding ? try clearing out and lubricating the inside of the caliper.

Easy fix, lower the brake pedal.

Change to organic pads instead of sintered.....

Buy a Ducati Multistrada as they come with NO back brake as standard.!!!:rotf[1]::rotf[1]:
