i have just fitted new brakes cylinders copper and flexi pipes al round my LWB series 2a and i have bled 3 times well and my pedal is soft on first puch then hard on second and then cant move it on the third puch could this be air still
or what could it be !!??

HELP ME PLEASE
 
ooh that would explain why mine are doing the same thing, hit the brakes and get very little pump the pedal once and stop in time hopefully
 
Springs
If it go's hard after 2 or 3 presses and then go's soft after 2 to 3 mins then you have the springs on wrong.
 
just fitted the following to my mk 1 disco 92 2.5 tdi manual.
2 front discs/
copper brake pipes and fittings/
brake pads/
4xsprings/
4xshock absorbers/
2xshock absorber turret rings/

NOW! my brakes are crap?, bleed till i used enough fluid to run a battleship.
pedal goes half way down (with slow creep)then stops rock solid?,
pump and they come up and are ultra efficient,
fitted a brake servo check valve?
and servo service kit,

this all means i am scared now to drive the thing in case they fail
and especially when i take my grand children in the thing

only things i havnt changed are: 1/complete servo replacement
2/ vacum pump service kit/ and or/ replacement

can anyone help please

Your brake shoes are likely too far from the inside of the drums. Check them, and if you cannot get the rearward shoes of the rear wheels to contact the brake drum, then you have the wrong shoes in those positions. If you look closely at your rear shoes(line all 4 of them up), you will find that there is a difference between the forward and the rear shoes. The rearward shoes should be the ones that have its adjustment peg higher up on the shoe. After you get the right ones in, readjust the shoes.

You may have better luck reposing this in the disco section.
Us series owners dont have fancy things like servos or disks,for the most part.
 
I am having the same problem on my SWB S3, having to double press the pedal,

new cylinders, pipes, shoes, etc..

i have checked all the springs and they are ok, and that i have the correct shoes for front and rear, and i have checked there is a decent vacum going to servo, but i dont know how to check the master cylinder adjustment rod, i have looked in the book i have and it mentions nothing about adjustment for the master cylinder and looking at it reveals nothing obvious. can anyone point me in the right direction please

Not too sure where to look on a servo system but its the point where the pedel joins on to the master cylinder.
 
Ahem I adjusted mine.....

Brake pedal was sooper, brakes so good....

Left for work......




And ground to a halt 5 miles away with smoking brakes, I had adjusted em a wee bit too much, so that the fluid did not 'flow' back, had to do a hasty adjustment, seem OK now and brakes still pretty good....

Oh well you learn something new every day....

so i presume if i remove the 2 bolts that secure the master cylinder to in my case the servo i will be able to access/adjust the length of the rod? is this achievable without having to break into the hydraulics (sick of bleeding them!)

cheers

I have brakes!!

after putting up with this for too long, and having looked at this problem on and off with no fix, i started from the beggining today with checking the springs and shoes (both correct, although wear on the shoes seem uneven) i then fully backed off the brake adjusters on each wheel and bled the system, i must have gone through half a bottle trying to get 'clean' fluid through, which was a bit worrying as it had new fluid end of last year when i renewed the cylinders, brake lines and shoes. I think the fluid might have caused a few problems, when i changed the lot last year, i had the system open to the elements for about a week waiting for parts, so i think this must of introduced water or something into the system (schoolboy error!) after bleeding i tweaked up all the brake adjusters, and that was it. I have never experienced series brakes that will lock all 4 wheels before (standfast a hybrid S3 with discs) all be it if they are helped by being dual line servo assisted brakes, but at last they work and dont pull to any side! i just need to practice a bit of right foot ABS.
