poop brakes - help

Post by benlg81 »

Hi all

finally got round to bleeding all the breaks on the rocco last weekend and still no joy the brakes are poop.
The rear shoes have a good few mm left on them the front discs and pads are good.

i had a look around the master cylinder and found this

any ideas if it is a seal replacement or a full replacement?

any ideas where best to get either part to fix this issue?

Nowt wrong there, fluid will not be going anywhere near the linkges at the back of the servo :good:

Apart from any leaks from the lines themselves i'd be inclined to check the rear cylinders aren't leaking!

Does the pedal stay spongy when you pump it?

If it's got drums on the back, try tapping the adjuster wedges in the back wheels back up and start again. You can normally do this through one of the holes in the drum if you don't fancy taking the drums off.

I had to knock them up about 3 times when I bled my polo because they weren't letting the cylinders return properly so they kept getting air trapped in.

Just knock the wedge straight upwards. Give the drum a whack with the mallet to return the shoes, then carry on bleeding it.

could do with some slightly better descriptives. there are many ways brakes can be poop. pedal sinking, excessive pedal travel, locking up as soon as you look hard at the pedal...

sory mate the pedel goes half way before it does anything and then not a great deal happens after that, they can lock if i leave it very late but that is rare.
i have got used to the brakes now but my wife cant get used to it

with the engine off, pump the pedal a few times, then push hard on it. does the pedal slowly drop to the floor? if it does, then fluid is coming out somewhere.

i suspect that it is more down to drums and/or crossbeam mech being way out of adjustment. make sure that the adjuster wedges haven't worn (my caddy has done this, the brakes will keep unadjusting themselves. really not helpful for having good brakes)

with the wheel off, rotate the drum til you can see the bottom of the wedge thru one of the bolt holes. get someone to stand on the pedal really hard and then force the wedge down with a hooky-pokey thing. do this both sides, you should then have a handbrake that operated on 1 or 2 clicks, and a much improved pedal feel.

check for any play in the crossbeam mech. this can be adjusted out, but if you adjust too much then the brakes will drag.

it's also worth getting someone to stomp on the pedal while you hold the flexi hoses. check for any signs of the hose bulging under pressure. if any of them do, replace them. good excuse for a set of braided hoses ;)

You can get the drums from GSF and also new shoes (with new springs!), may work out cheaper.
