Question Sierra Master Cylinder Pushrod
A quick question, excuse my ignorance, but never having seen one before, what does the master cylinder pushrod look like?. Is it M6 Bar threaded at just the one end that goes to the pedal clevis, or is it threaded at the master cylinder end as well, or just pushed in?, & approximately, how long is it?.
I've never taken a master cylinder apart, so it's new to me what exactly I need, cheers, Dave.

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.
