FJ1200 ABS brake nightmares- sticking on abs flashing

[Ann]

Hi all,  firstly thankyou for   approving me  on the forum
I got a FJ1200 that has sat for 4 years, and so the  callipers were  dragging. So i   systematically removed the pistons one at a time,  removed the  seals,  cleaned all the crud out and fitted new piston seals to all  8 pistons at the front and the the two at the back. I made sure i took my time cleaning the crud in the  seal channels, Used  none genuine seals and Pyramid  brake pads, which i had to  remove the paint on the edges on the one pair as they wouldnt fit the  calliper. Since then  the brakes were fine until a test ride in which the ABS  kept flashing and the the brakes are now binding on worse. There is an issue with the rear disc being cracked, which will be replaced with new  disc and pads.
Im looking for  tips as to why
1- the  brakes are now binding after a test ride( im thinking the pads are binding, as i had to file one set to remove paint- calliper had no corrosion in pad travel area)
2- abs light flashes constantly
3-  how to bring up fault codes, to see what ABS fault code there might be

Any other advice on this braking issue would be  much appreciated, thanks in advance

The pads are not retracting. I suspect the problem resides in your master cylinder. The reservoir gets full of crud and at the bottom is a relief port that gets plugged. You have to remove the splash shield at the bottom of the reservoir to properly clean this area.

Welcome Ann, I hope this helps.

Well I pushed dirt into the bores when servicing my ST years ago because I didn;t clean the extended pistons of crud when I pushed them in to fit new pads but this is not your problem. Hoses? disconnect ABS?

Hi Pat,
thanks for the reply, i will look into that, as you could have  point as its stood for about four  years unused ,  brakes were binding  badly, once   rebuild they were free,  after an aborted  test ride they were   hot and dragging.. with abs flashing.
you you  could be right

Its just funny it was  fine  until a test ride, im  kind of guessing ABS  valve sticking, blockage like another reply mentioned. Front hoses are upgraded  braided  type.  It will be friday before i get a change to look at it  again
