brake Q's
Hi,
Does anyone have any photos or advice on the best way to make the push rod that goes into the brake master cylinder? Also when tightening the joints
on the brake lines can i just do them up or do i need something on the threads like ptfe tape?
Cheers
Dave

You shouldn't need PTFE tape but equally some people use it (even if it isn't official brake fluid safe).

I used a short length of threaded rod, just round off the end for the M/C a little.
PTFE tape isnt needed, the seal is from the flared pipe ends not the union threads

Please PLEASE do NOT use PTFE or any other tape on brake connections! 
As big rich says, the seal is formed by the flare deforming slightly to produce a seal....

Hi Dave,
Merlin Motorsport sell a purpose made pushrod and clevis assembly which does the job very well.

NO to PTFE tape in the brake line joints and don't overtighten them either.

I used an 8 mm bolt, sawed the head off and file the end to be counded then screw into an 8 mm clevis with a lock nut.
This makes it adjustable and if a rubber cup is fitted, can't remember if I have one or not, the unthreaded shank wonlt be filing away the
rubber cup.
