Brakes Again

[eupho]

I have spent time viewing very many posts on brakes. So, I have a common problem, i.e. the pedal travel is FAR too long...not at all reassuring. However, having done all the usual, i.e. pads, bleeding(3 times) they are no better. However, is this a clue...the rear discs work but only when the pedal is first pressed; with the pedal held down the pressure releases. This leads me to one conclusion, that the master cylinder is finished...i.e. the fluid is finding its way back past the piston.....a bit like the old bike pumps with their leather washers, the air would escape past it on the pump stroke. I think I am being logical...unless of course you know differently. Incidentally have priced up new master cylinder...staggered by the various pricing! As the Haynes does not cover the V6, am I right in assuming that the job to change it is the same as on the other models?

Thank you in anticipation !!

...could also be the brake compensator valve, remember that the rear which operates is also linked to the opposite front; ergo very poor brakes.

 

1) Can you lock up the fronts braking in a straight line?

 

2) Does the pedal slowly sink if you hold it on after first application?

 

3) Does pedal travel decrease noticeably if you leave the handbrake almost on?

 

If 1) then compensator valve, if 2) & 3) then Master Cylinder.

 

 

Hope this helps.
