Sierra Master Cylinder Pushrod

[baz-r]

the sierra has a servo so its hasnt got a pushrod there is a plan in the book to make one.
its basicly a long bolt and lock nut with the head cut off and flat end rounded
i found a cheap and easy sorce of clevis's is from trailer suppliers for my pedal box but its not a haynes one

I've seen the plan in the book but is the rod just a push fit into the cylinder?, also how long a bolt do I need to start with, would studding be ok?, I've got an M6 clevis for the pedal, Dave.

m6 is way to thin and studing would be weaker and softer than a bolt you want at least m8 8.8 bolt or harder im pritty sure the book uses a imp size

a too long bolt could always be cut shorter

The book actually says M6, but I must admit it seems thin. If I go for an M8 bolt, what length to start with, so I know what to buy?

A trip to the breakers and you will find one or ebay http://www.ebay.co.uk/itm/Triumph-ST...item43a9de9e32

Might not be worth the making.

There is a pushrod of sorts on the Sierra from the pedal into the servo but this is no use on the roadster,as sugested make one from a decent sized long bolt and clevis's are available from Rally design.

I personally would suggest you make it when pedals and pipes are all sorted as you need a full stroke of the cylinder for efficient brakes.

Thanks all, I just need to know the length of the HT bolt I need, hope to get it locally Monday. Will a 120mm length be ok?
I have the pedals sorted and am doing the pipes and flexi hose this week. I just have to open up the master cylinder mounting bore on the pedal box first to about 40mm for the cylinder fitting.
