after that sinking pedal feeling on the way home from stoneleigh, it looks like i need a new master cylinder
apparently there were 2 manufacturers for a 1983 2l sierra
are they interchangable or how do i tell the difference ?
the only marking mine has is ford on one side and 311688 k023g which means nothing to my spares man
3 oulets 2 at front one at rear
picture in my archive
Dave - you may be able to get a set of seals from Ford, no?
We had a similar thing - turned out to be only the last seal before the push-rod assembly.

maybe yes, maybe no, either way its booked on a track day for saturday and i need it right !!
It's very difficult (impossible it seems) to get a seal kit. If you find a source let me know! I wonder if anyone has found a sutiable
alternative, it might be the quickest way to get it fixed (if a littel hard on the wallet!)..
As far as I know there are two types. One is a smooth black cylinder the other a cast gold item..

Get a VW Mk1 Polo or Golf (non servo) mastercylinder very cheap brand new from Euro car part but you have to get the resevoir from the scrappies.
Brakes international have m/c service kits (which i assume are the seals etc).
They also have pictures of the different types of m/c so you can check it's the right type.
Never used them, so don't know what delivery times etc are like.

When you've found the master cylinder click on the associated button to get to the service kit.

No use to me as i#ve got for an alloy nissan jobby.

Brakes international have them on the site, but if you click the button to order them you'll find they don't actualy do them anymore (at
least last time I tried)...

I have removed mine and put it back on.. Bit of a sod as it's very hard to get off.. As you say you might split it where the tubes come out if it
comes off at an angle..
Dan
pulling the reservoir off is a pieve of cake - you need to angle it to one side and pull.
getting it back was trick, at least for me - I just could not get it to go into the new seals which seemed softer than the older ones, as the old ones
looked fine, I used those.
can't recalll if it was just the selas casuing the prpoblem but think I plumbed in the master before fitting the reservoi so did not had the full
movmenet for pressin it in.
I have a leaky cylinder in the shed and when I looked at a kit to repair it I decided to get a different one. The kit came with a piston, spring and seals and cost over £30.
If the mc has a plastic band with numbers on it loosly around the middle the numbers are the part number as opposed to the casting number. Don't
know if that helps.
Also if you have a lucas centre near you I have found that they can be very helpful.

thanks for all the pointers
found a local motorfactors that had one at another branch
top came off and went back on easily..
fitted, and partially bled, ran out of fluid.. will carry on tomorow
apparently the only difference is the spacing of the 2 fixing holes.. ones 90ish mm and mine is 70ish
mines the bendix one

A new VW cylinder is a lot cheaper than the Sierra repair kit !
