brake servo removal

[roulli]

Help!!

I need to remove the servo, removed already the 4 nuts in the footwell, but the servo doesn't move at all.

I hammered against the bolts sticking into the footwell, triesd to lever the servo with a wooden stick- nothing happens!

Is there any trick, or do I need to have some spinach?

Thanks for any hint -Patrick

I take it you've removed the brake pipes from the master cylinder

and the pedal linkage

Harry,

no I didn't as I can also "move" the master cylinder out of the way, without removing the pipes(they're flexible). I did that according to the bible in order to regulate the play on the pedal, without succes however, as the play is coming from the freeplay of the bolt connecting the pedal to the servo rod.

Thanks for your hint anyway, could be the pipes under tension give to much of a momentum to the bolts of the servo, so that they get hooked up in the holes of the footwell. I'll try to remove the master cylinder from the servo.

Yes I did, thats why I want to remove the servo.
I need to bring the holes of the servo rod to the same diameter than the one of the pedal. Then I will get a bolt adapted, 1/10mm thinner than the holes, and the sloppy pedal should be passé.

For the time being:
pedal hole: 8.5mm
servo rod holes: 8.15mm
bolt: 7.8mm

Had the same issue. In the end the only way to shift was too apply direct force onto the end of the bolt using a hammer and punch.

Mine wasn't stuck as fast as yours sounds like it is though !

When you put it back make sure you put it back exactly the same way as the bolts are offset and it will only go back the way it came off.

Haven't followed what you're trying to do, no doubt it will be fine, just to check though: you're aware the pushrod from the pedal to the brake servo has to be free to wobble to take up the misalignment as the pedal moves in an arc? This is nothing to do with free play in the pivot of the pedal itself - which may be what you're talking about, I don't know.

Peter,

what I mean is the freeplay between the linkage pedal to pushrod. This linkage should only allow to pivot around the bolt. The pushrod fixation in the servo allows to take the misalignment due to the pedal moving in an arc.

Hope to meet you in Zolder

P.S. I managed to remove the servo - now I have to through up from all that spinach...

Aha now I see what you mean, yes that is just an ordinary pivot and play in it is uneccessary and undesirable.

Looking forward to it already - watched last years videos over the weekend to remind me what fun it it was. Wonder what extra changes they've made to the track this year?

They'll be a new moving chicane. It will be at random poistions around the circuit and will be Arabian Blue and controlled by a Freak with a very large grin and plastic pants.

The only way to enjoy a full unadulterated lap of Zolder this year without the necessity to avoid this lumbering idiot will be to take the controller for a spin round the circuit for a couple of laps in your own car.

So Peter, you'll be alright as you have already committed to do this. It is just evidence of how well prepared you are when it comes to these kinds of events.

Patrick, unfortunately it looks like you'll have to concentrate on avoiding the Arabian Blue mobile chicane unless he is in Peters car in which case you could follow them, there is a good chance he will be in couple of Cerberras at some point and theres a good chance of him being in a couple of wedges aswell.

Changes to the mobile chicane will be notified to those that know him !!!!
