MK5 Cortina Brake Master Cylinder

[nigelghia571]

Help needed again please.

03/81 Mk5 2.0 Cortina

Have a slight leak of fluid between M/C and Servo.

I understand there are 2 types of M/C that could have been fitted - Girling and Bendix.

What are the differences and how can I identify which one is fitted?

 

Thanks aging for any indications.

The spacing between the two bolt holes (where it attaches to the servo) are different.

 

Here is the wrong servo on my Mk5 - the bolt spacing is different by quite a lot

 

 

But otherwise they're quite similar:

 

 

However, I couldn't say with confidence which is Bendix and which is Girling

Thanks for the reply.

I will measure the bolt centres on my Master Cylinder.

It looks like you have managed to get a new master cylinder??

No, I could only find the smaller one, so cleaned up the old one.

[nigelghia571]

Measured mine.

The bolt holes are 3 1/4 " spacing.

Missed one this weekend at the NEC as I wasnt sure of the bolt spacings. Turneed out it would have been the correct one.

Where did tyo get the smaller one from?

Just some guy on ebay. Something like this:  http://www.ebay.co.uk/itm/271787041920

 

But you can get both types at Old Part Store:

Really, I should get off my bum and get a new one myself while they're available...

Just coming to do this job soon.

How difficult is it to remove/replace the Reservoir?

The plastic looks fragile!!!

Its a doddle. Just prise out gently. Bleeding the brakes after is more difficult than changing the M/C itself IMHO.

Thanks

 

What's difficult about bleeding the brakes afterwards?
