The Classic Marque

worried about brake man--The holes in the end of the piston do nothing really as far as the workings of the cylinder go,2 are plenty enough, they're just there as a vent/bleed to stop any pressure buildup between the two seals so the primary cup can fully return to the rest position --some (different manufacturer) have that main cup actually in a groove on the piston like your secondry cup, other...

Very small contact area with the end of the cable and I think the part is wedged in there pretty tightly.
But I will try anything Trev!

One of the rear rubber check straps has broken on the Frog. They were last replaced in 2010. I read that replacements are poor quality and last a matter of months. They are certainly cheap!. Any recommendations

Fair comment about the oft-mentioned CnC, Richard - but in my case the cylinder does not need any attention - it has a perfect resleeved 1" bore; it is only the piston, non-original and of no known origin, that is not doing its job properly. Doug Pelton has suggested that if I can't find an original, I have a new one made by a machine shop. Good idea - but I would still need (even just borrow) an...

The MG YA/YT uses the same Master Cylinder and long time ago, dates distant memory for me but will be written in my maintenance book, I had purchased a reseal kit and could not get the brakes to bleed, kept sucking in air, ended up getting C&C to re-sleeve my one for the YT I got a second re-sleeved and rebuilt and have it somewhere amongst my many parts and I got old knackered one for the sake of...

How about a really strong magnet? I know it will stick to the spindle too but when you pull it off the cable might come with it.

The hardness of the steel has no effect on its stiffness.

A nice idea Richard. I have already tried to get a self tapping screw to bite but couldn't get it started. The wire strands seem quite hard which rather surprised me when they do need to flex a bit on use.

Guy,

Just a thought if you have any very small taps - assuming the cable is of the curtain wire type- can you screw / force the end of a sharp fine tap in to get a bit of purchase ?
Probably need to be 7/8/ 10 BA but don’t snap it off !
Maybe a scriber point first to open it up a bit.

As I said just a thought !

Thanks aAnamn. That link is both concerning and also a success, of sorts!

<<after a couple of hours under the car I got the cap off and the 24 tooth drive gear out. Not an enjoyable job.Then I found there was no output shaft speedo drive gear fitted! >>

So in the end in his case, getting the gear out wasn't helpful as the corresponding snail cog on the output shaft wa...
