How to mod a late booster for MK1.

[foc64]

Peter, quick thanks for the info in this post as I've now modded and installed a Cordoba booster & master cylinder in my MK1. Haven't been able to test the results yet as I still need a few things like suspension, brakes and wheels to set the car on to terra firma!

Loon: Does the Toledo set up just fit straight on pretty much?

Yes it has the correct clevis pin arrangement. It must come from a car WITHOUT abs though, as those boosters are on an angle!

and only have 2 ports

twas just about to fit a cordoba booster modded as per Petes instructions when the vacuum pump died!

I have actually modded three now, one for each of my cars and one for a friend. I decided to use tee's to enable the use of the hydraulic brake light switches. For each tee (removed from the cordoba the booster came off), im having a short section of brake line made up.

cool idea, saves some wiring up i guess - personally, i like the change to the pedal switch because it really tidies up the engine bay

i used to repair Mercedes / ate boosters in the 80's
they can be opened up and altered other ways as u would know

Hey all, I have a Cordoba Booster and MC, but the MC only has 2 outlets. Anyone know if I a 4 outlet Cordoba MC is a straight swap?
I.e, will it fit up to the brake booster, the bolt holes look to stay the same across most MCs but what abt the rod connection (booster > MC)?

Don't want to have to replace the booster as well if I can help it!

yes, it should be. the 2 outlet one is for abs cars, hte 4 is for non abs. straight swap.

Thanks for that, I've posted a 'Wanted to Buy'..

Was thinking of drilling and tapping my 2 outlet MC..
The casting is structured as if it was made for 4 outlets, but only 2 were drilled in the factory.

I figured I could remove the internals then drill and tap it to the required thread.

Does anyone have any experience with this? Kinda hesitant to mess with it if it is potentially dangerous..

Hey Pete. I'm in the middle of doing this atm, any more info on how you wired up the switch/relay?

EDIT: some more info.

I've got the reed switch & 30A 4 pin relay.

The original setup has 3 wires:
-Red w.Black
-Blue & Brown
-Red w.Yellow
I've located all these going into the back of the fuse box.

With the relay I've got:
30 - 12Vdc
85 - Earth
86 - ?
87 - ?

with the switch:
Com - Earth
NC - ?

Pretty sure I have to connect the NC to 86, and 87 to the taillights. Or am I way off?

TIA!
