hardly any brakes - karl1989 - 10-04-2013
hi guys so i have no brakes. well the pedal is at the bottom and touches floor does stop but its not good. it has ABS. recently fitted a brake cylinder in the rear drum and the bleed nipple came loose not long after so lost all fluid. sorted it out now they have gone again. changed master cylinder and they did'nt build any pressure to bleed them but with abit of time i got pressure and the the brake pedal was near the top
but now i am getting full travel again to the floor 
. also the pipe that runs across the top of engine normally bolts down to the TMIC were it bends there is a T piece it seems to be blowing/sucking air in so have blocked that off if people get were i mean. sorry for the cr*p write up.cheers karl
RE: hardly no brakes - Toms306 - 10-04-2013
Erm, sounds like you have no servo assistance...you need that vacuum pipe between the servo and the engine...
RE: hardly no brakes - karl1989 - 10-04-2013
the metal pipe?
RE: hardly no brakes - Toms306 - 10-04-2013
Yeah, it should go from the brake servo to somewhere on the engine (vaccuum pump on an XUD I reckon), without it your brakes will be the same as they are with the engine off.
RE: hardly no brakes - Piggy - 10-04-2013
you've made your brakes rubbish!
Why did you do that?!
RE: hardly no brakes - Tom - 10-04-2013
Somethings f*cked by the sounds of it... How does the pedal even get stuck on the floor? Surely that means theres completely no pressure in the system, like a seals broke or something? Sure you dont have a bleed nipple open or something? Or the master cylinder is shot?
RE: hardly no brakes - Rich306 - 11-04-2013
Sounds like you are pushing all the fluid out, Is the Brake fluid pod still full up?
RE: hardly no brakes - Piggy - 11-04-2013
maybe he decided to disconnect other usual pipes?!
RE: hardly no brakes - Dum-Dum - 11-04-2013
It wont be a servo issue if the pedal is going to the floor, you have air in the system and/or a fluid leak.
Check for leaks and bleed the whole system with fresh fluid.
RE: hardly any brakes - gareth7 - 11-04-2013
^this, servo/vacuum issues make the pedal as hard as hell.......
RE: hardly any brakes - karl1989 - 11-04-2013
The pedal does'nt get stuck on the floor! It travels to the floor hence no brakes hardly. Yes theres still fluid in there i changed the master cylinder too. Will have a double check over it again at the weekend
RE: hardly any brakes - Dum-Dum - 11-04-2013
Gotta be a leak or air bubbles if your going to the floor.
RE: hardly any brakes - Toms306 - 11-04-2013
I've gotta say it's not the best description lol, I didn't even realise the pedal was going to the floor. If thats the case then I agree with the above, a leak somewhere. Dd you only change one brake cylinder? Maybe the other ones popped and dumped the fluid into the drum?

having it incorrectly fitted would also cause your issues. Are you sure you fitted it correctly?
Likewise, borked master cylinder seals would put the pedal to the floor.
RE: hardly any brakes - DarkInferno - 11-04-2013
or buggered rear brake shoe adjusters.
RE: hardly any brakes - karl1989 - 11-04-2013
Yes i only fitted 1 cylinder. Theres no fluid leaking that i can see. Also the brake pedal gets pressure when the car is turned of but when running they dont build any pressure
RE: hardly any brakes - Ruan - 11-04-2013
Yeah, that just proves the servo is doing it's job.
You've either got a CHRONIC airlock or it's pissing the fluid out.
RE: hardly any brakes - Rich306 - 12-04-2013
If you're not losing fluid then i'd say definitely Airlock issue.
You been bleeding them properly? you start closest to the master cylinder and pump slowly to get the air out.
RE: hardly any brakes - Slam Wagon - 12-04-2013
Start at the furthest isnt it?
RE: hardly any brakes - Dum-Dum - 12-04-2013
Have you definitely checked every centimeter of the braking system and all around the calipers and drums on a perfectly dry day for the leak as sometimes they are very good at hiding.

Lol my bad :O
RE: hardly any brakes - karl1989 - 13-04-2013
rear brake cylinder gone. went for a long drive and noticed its decided to bust the seal on it
RE: hardly any brakes - Piggy - 13-04-2013
the other cylinder or the one you replaced?!
RE: hardly any brakes - karl1989 - 13-04-2013
the other one. cant wait to get the HDI axle on now
RE: hardly any brakes - HDIkyle - 13-04-2013
The other one it is
RE: hardly any brakes - karl1989 - 13-04-2013
ye the old one not the new one
RE: hardly any brakes - Toms306 - 13-04-2013
Woop...I was right then...second time round lol. Exact same happened to my ph2 1.4!
RE: hardly any brakes - Eeyore - 13-04-2013
definite leak. My 1.4 I ran out of fluid and the pedal went to the floor and i couldnt stop... yay!
RE: hardly any brakes - karl1989 - 26-04-2013
the problem is the rear cylinder found out ages ago
