Hi I am new to this forum and am looking for some advice. I hav3e a 1990 k100 Rs 16 valve with ABS.

Recently I have noticed that when riding and I apply the rear brake everything works ok for abour2/10th of a mile then The rear brake seems to stick when pressed down about an inch then it will not move at all when pressed, you can stand on the brake lever and it will not move. After this happens the ABS warning lights come on and the brakes return to normal use. All this happens in 3/10s of a mile.

No-fault codes show on my monitor and each time I reset ABS system the same thing happens. I have replaced the ABS brain with another and the same thing happens. I am about to replace the rear modulator as I can't think of anything else.

I would be grateful for any help.

Thanks 

Ian

Do you still have the original brake lines on your bike?  What you describe sounds a lot like the lining collapsing in the brake line.  This can cause trouble in two ways, first is that it only allows the brake fluid to flow easily in only one direction, holding the pressure in the caliper.  The second way is by shedding bits of rubber that plug the banjo fittings, usually the plugging is at the fitting on the caliper.ABS System Overview Dscn3012
