poor brakes mk1
« on: March 28, 2017, 11:28:23 AM »
Hello chaps,

I have 1998 90 bhp Alhambra 210000 miles and i cannot seem to get a decent brake pedal.
So far i have changed 3 calipers
bled the abs pump with vcds numerous times
changed the vacuum line from servo
changed the rubber grommet at the servo
changed servo vacuum pump
i have also swapped out the master cylinder.
All tests on the servo holding vacuum seem to come back correct so i am at my wits end.


Thanks for your time
Mark...

I should also have mentioned that i have manually bled the brakes, and also used a Vacum bleeder, bled out master cylinder. no weeping brake cylinders, pedal still sinks to near the floor, no leaks that ic an spot and she has been sitting for a month or two in the drive way.

Thanks again

Sinking pedal is usually master cylinder seals leaking between ports internally so will not be visibly leaking fluid externally.

Hiya ransome :)
Some new some taken from a Sharan that was rotten, but had good brakes.
Me and my brother have been over the brakes again and again, the two Alhambra"s my brother owned never had this problem, one was a mk1 and the other a mk2 and we changed discs pads and the two brake pipes that run the length of the motor, i dunno i am sorta stumped!

Thanks again Mirez 8-)

In the meantime haha today is another vcds bleed, with a pressure bleeder on the master cylinder, and a vacuum bleeder on the nipples, i have read of doing an output test on the abs instead of the abs cycle bleed, any thoughts anyone. can you bleed the rears through the output test.

Your a very helpful bunch of like minded scallywags, and a decent crowd of guys.

I have heard on some vag cars they needed the abs output pump activating several times to shift stubborn air bubbles from abs block,after being done air suddenly released from rears.
Not had an issue personally but a mate had a golf that was a pig to bleed after having system drained for brake pipe change,he ran pump in output test about 5 times and on last time did a manual bleed at same time. He did manage to get a decent pedal eventually.
You might need a charger on as running the pump drained battery

Is this a problem that's only been evident since you've worked on the brakes or did you work on the brakes to try to solve this problem?

Hard to bleed brakes on a Mk1 is something that's been mentioned before on this forum but in that case it was on a non-ABS model.

How you doing Insanity beard,
The pedal has sunk since i bought her 5 years ago, went to bleed the rears for this MOT and the bleed nipple sheared flush, after i changed the rear caliper i had no pedal at all, now i have a decent enough pedal but it still sinks to nearly the floor. 
Yesterday with a pressure bleeder on she gave some tiny bubbles from the rear off side, the side i changed, but they where very tiny bubbles and made no difference to the pedal.

Thanks for the encouragement Jonny,
i will keep plugging away at her and in the end i will get to the bottom of this.
I tested her a few weeks ago and she passed the MOT brake  test, but the guy failed her on the pedal travel.
I can see the Mot tester point, i know about pedal creep but this is a bit beyond comfortable ;)
I have two spare batteries and a good charger, and although my brother does the laptop stuff while i run around from wheel to wheel (fronts) we have done quite a number of abs bleeding on vcds, the out put test we have not tried yet.


Once again chaps thanks very much for taking the time to help,

Hello,
today i am changing the ABS pump for a laugh, i have one here so i may as well.
Over the weekend a new master cylinder was fitted, but made no difference.
This MC was brand new and bought with the understanding that if it made no change i was to bring it back, so it was returned this morning pronto.


To Mirez, looks like i will not be needing that Mc, after this ABS pump change the only component left will be the servo,
so sorry for saying one thing and doing another Mirez, sorry. I might be in the market for the servo alone though hahaha


I"ll let you"s know how it goes :D

Well chaps,
ABS pump changed with no problems, pedal no longer sinks completely to the floor, i"ll not say she is right just yet but changing the ABS pump has made the biggest difference, no the "only" difference.

Calipers x3
Master cylinder x2
Vacuum pump
Vacuum line
Servo grommet
N 75 valve
All Vacuum pipes to and from N75 valves renewed
Pressure bleeder
Vacuum bleeder
Vcds x 7 ?
and an ABS pump.


Think i am starting to see a bit of light at the end of this dark tunnel  :P

Hiya Chaps,
Well after we blanked the two outlet on the MC today and had a rock hard pedal, it was time to think again,
my brother noticed one of the rear bleed nipples was twice as long as all the others, we changed the nipple and my pedal is back to where it once was.

Me and my brother David now believe it was the ABS pump and the wrong rear bleed nipple, the threads on the wrong nippple looked a bit worse for wear, dont ask me to explain the nipple thing as the caliper was taken off another Alhambra, complete with nipple.
Bit of welding then another MOT test and i am sure she will pass.

Thanks for all the help guys and i"ll try to stick around :-\

Hiya Chaps,

Well after all my troubles the old wagon is once again passed fit for another year, me and our David welded up the offside out rigger, put the wheels on and she flew the MOT, front brakes are in around 80% with brake fluctuation at 11%.
No advisories not even a tire.

If you happen to be having brake problems, ie pedal sinking to the floor, check your calipers along with a close inspection of any bleed nipples.
My original 110000 mile Master cylinder has been re-fitted as is fine.
My sinking pedal was not a problem related to the MC or the reversing seals idea.


Once again guys thanks for putting forward some fine ideas and thanks to Mirez for the offer of parts.


Mark...
