did MK build it, if not, what master was used ?
the place i used for brake parts was https://brakeparts.co.uk/shop/Ford
they includes pics so worth a look, they also give part / tag numbers as well.

Likely to be a Sierra 22mm cylinder, which doesn't work very well so I would swap it for something else.


bazz81 - 25/5/18 at 03:06 PM

I think its a Sierra m/c but dont know. I made 3 photos but dont know hoe to upload in this topic. I added them in my photo archive, can you see them?

What m/c do you recommend? And is this a direct replacement? The Indy is in workshop and dont think they want to convert to another system if its a lot of work.

I have a MAC#1 ( very similar to MK) with the donor sierra M/C and donor front/rear brakes, it works just fine.

that looks like the master from a sierra, the one most people go for is a NON servo fiesta MK1, downsizing on the bore makes a huge difference to braking performance.

Are the masters of a sierra al the same? M/c must be shipped to Holland so i dont like to order x-times becouse it wont fit.
Is the fiesta also a direct fit?

Is this the one i need?


SJ - 25/5/18 at 05:43 PM

Aren't there any motor factors you can take it to?

As far as I know most non-abs Sierras don't have the same mc, but can probably be easily made to fit. Mine came from a 1990 1.8 cvh Sierra Sapphire and is 22mm dia.

Any idea what the donor car was?

bazz81 - 25/5/18 at 05:48 PM

I dont know the donor, i bought the car in Holland. So i think im the third owner. Car was build in the uk.
They told me i have a 3:14 diff, in what models was that diff installed.


SJ - 25/5/18 at 06:43 PM

Problem is if you don't know it was built from a single donor the bits could have come from anywhere.

If there isn't a brake supplier you can take your old one to you will have to take a chance. £50 isn't much of a risk.

Only other option is to get it refurbished. What's actually wrong with it?


SJ - 25/5/18 at 06:49 PM

This is the one mine came with:
cvh
Looks very much like yours.

unfortunatly there seems to be loads of different master cylinders, there is normally a plastic tag on the body that is the ID number you need.
no idea if a fiesta cylinder is a direct fit, probably pretty close, i change mine for a FIAT 127 one, it was brilliant but took some mods to make it fit.

Is it possible to measure the centre distance of the mounting holes, and the holes of the reservoir? so i can check it with my m/c

Sorry, I swapped it for a Fiat 124 non servo mc a couple of years ago.


bazz81 - 26/5/18 at 08:12 AM

Okay no problem, thx for the reply


Dick Axtell - 26/5/18 at 04:44 PM

If you still want to fit the Sierra mcyl, I have an old, but unused, one available. Still attached to its servo-booster, I had it for an installation check (when still at work).


bazz81 - 27/5/18 at 07:24 PM

I dont have a servo booster so will it fit ? Can you make a photo and the dimensions/measure it for me?


SJ - 27/5/18 at 08:43 PM

All Sierras had servos fitted as standard. The reason people change the standard mc on kits is because they tend to be used without servos so need a really firm push if the Sierra mc is used

Wouldn’t it just be easier to get it from mk instead of trying to find the right one for your
breaks, as there is different types for different breaks!

Will be able to do so when I get back to my lock-up. Hopefully tomorrow.


sebastiaan - 28/5/18 at 06:08 PM

If it is an Indy, there is a 99% chance you need a standard sierra master cylinder. One of these should do, and they are cheap enough to take a chance.

brake master cylinders

Good luck.

Here are the photos you asked for. Side view first -

Sierra_Mcyl_Side_1
Sierra_Mcyl_Side_1


And the end-on view -

Sierra_Mcyl_EndView
Sierra_Mcyl_EndView



Mounting holes on 90mm dia circle, with holes set at 30 deg to horizontal. No input rod, 'cos the servo output rod provides this action. If you already have this mcyl, I presume you have the necessary pedal-connected input mechanism?
