mates vy ss no rear breaking problem

[Luca_VY]

Thanks for the info Big-Al, will get it towed to a specialist. I find it suspect it was fine on the way to work but stuffed on the way home.

Haha Luke you found my source of all life's hard questions, cheers guys for help

 

[Big-Al]

Also have you checked the brake fluid reservoir? maybe they forgot to tighten a bleed nipple up or a hose has perished and leaked all the fluid out.

 

[Kiddo]

If all the fluid had leaked, he'd have no braking at all. Not fun.

This is what I think is weird, I haven't had the time to check it out as yet. The pedal is harder to depress, and I can feel it's the rears as when it pulls up it rocks back as if all the pressure is pushed forward. Are the rear brakes independent to the front

 

[Tree cutter]

Yes the rear brakes are independant to the front. If you take the cap off the master cylinder there should be 2 chambers for the brake fluid. One is front the other is rear. If one end of the brake fluid resevoir is empty then you have a leak somewhere that you need to fix. If both chambers of the master cylinder are full then you have an internal leak in your master cylinder if your rear brakes will not work.

I had it up yesterday.
The reservoir is full on both sides. Both rears spin with the pedal depressed as Big-Al advised.
Spoken to a few people and they seem to think the master cylinder seal is bust (I have no idea what they mean). It's booked in for Monday, will see how we go.

Be interesting to hear the outcome in this and what was the cause.

Please keep up informed.

Turns out, it was the master cylinder. The piston for the rear was stuck. the mech couldn't really explain why, it just failed.
