I would like to thank everyone so much for your help and advice It has been so helpful and sorted out the issue, it was down to the 30 Amp Fuse on the Purple relay, it seemed to have got hot and melted a bit and caused the Silver contacts to perish. Swapped it over for a nice new 30 Amp fuse and all is ok, Breaks works as normal.

Thank you cozmeister as you said taking the dash out is easier trying to get to the fuses and relays.

This has saved me so much grief because i was looking at the wrong areas. Thank you all again

I topped up my brake fluid as i took some out and the Handbrake light goes out now when i put the handbrake down. The Abs light goes out when i start the car but when i drive off it lights back up. But this is how it’s been since last summer. I’ve tried cleaning the sensors to no avail.

Just out of Curiosity what are the other fuses for?

The Green relay with a 20 Amp fuse
The Yellow relay with a 20 Amp fuse
The Yellow relay with a 15 Amp fuse

and the purple with a 30 Amp fuse is for the breaking system

Thank you all again
