Thanks Silver Bullet,
Have ordered rear hoses both sides . A point of note . I jacked the car up on all wheels .
Tested master cylinder by pumping brakes with engine off . Kept foot on brake and started engine the pedal dropped an inch or so. Thus providing master cylinder OK . I read somewhere that was a litmus test to see master cylinder OK.
However because I was only checking rears . I thought let me just check fronts as car was in air . Found nearside front locking up ager just one or two presses on pedal. Repeated, baked from MC and wheel was free to turn . One press on pedal the wheel locked up.
So I have rebuilt front caliper , yet to fit .
In summary going to replace both rear hoses and refit nearside caliper and report back.
Thank you so much
