After a wait of several weeks, my new hoses arrived yesterday so I fitted them up this morning, ready for the great brake bleed.
Remember I'm starting from an empty system.
Step 1 in RAVE, as you’ll all obviously know, is to bleed the master cylinder. “Open bleed screw on booster, when fluid appears, close bleed screw” etc., etc.
Reservoir is full but, I’m getting no fluid at the bleed screw.
I've mailed Russell to see if he's come across this before after a modulator rebuild.
