Rear brake cylinder

[johnyfartbox]

Just rang my local car spares asking for a replacement and he said there was two types, cast iron and aluminium. This is for a TDI 75, 54 plate.
Didn't know there was a choice.
Advice please peeps.

It's ok guys, I found an old thread which says cast and 17.46 mm piston.
Hope that's correct, I'm picking two up now

Cast is correct. Perhaps the ally one is for the 1.2 tdi?

 

[johnyfartbox]

Not sure Audifan, im sure he said the Ali one was 15.20mm piston as well

 

[audifan]

Again that makes me think 1.2. You may also need replacement rigid pipe(s) as the nut tends to seize and pick up on the pipe when trying to remove from the slave cylinder.

Well did you sort your rear brakes?

 

[johnyfartbox]

I did indeed, first time I have done it and a resounding success .

That is good news. As I thought the ally / 15.20 are for the 1.2 tdi. I assume you did a nice flush and bleed afterwards - not forgetting the clutch slave as it uses the same fluid reservoir.
