Back brakes

[shadowryder]

O.N,Yeah it is only just higher than the frame at the front,it is still lower than the slave cylinders so I will probly need to fit a one way valve of some sort.
The shaft on the M/c is getting full thrust  and there is minimal play in the Idler so fingers crossed it will do what its s'posed to.
Thanks again to all who have commented/contributed to the post.

OK,I got one more question guys,
Where on the back plate is the optimum place for the slave cyls, when I first got this back from the builder he had mounted them at the top,
I was told by some one that they work better at the bottom of the plate so have since moved them.
I am thankful of any?advice that comes my way so which is it ToP? Bottom? front or rear?

Cheers All.

As long as the piston is pushing toward the leading shoe, I can't see that it matters. Even that should not matter if the slave is free to slide in the back plate, but they can seize if not maintained correctly.
 I have mine mounted at the front with the hand brake actuating lever hanging down. This gives me easy access to the adjuster from the rear, easy routing of the hand brake cable and also means that if the slave jams in the back plate I still have leading shoe braking.

If reversed from side to side and single action piston then they are as good as when reversing ie rubbish as they are designed to self servo when operating in normal direction of travel .  Double acting brakes it won't make any difference. I don't know which Reliant is though.

as ON has it is the way they are standard also the way mine are and seem to work ok although not road tested as yet

They are, of course, single leading shoe rear brakes, therefore the result is self explanatory! and " as it says on the tin", it matter not at all which way round the shoe/backplate relationship is, Morrag

Thanks Guys!!!

Same shoe will always lead ,yup agree with that . But in normal position ,viewing drivers side from curb, then leading shoe is to the right and wheel is rotating clockwise. So as brake actuates show is pushed towards drum by direction of wheel rotation.

Swap the drums side to side and again view the driver  side . Now leading shoe is at rear but wheel is still rotating clockwise. Brake actuation now pushes shoe back to starting position.

Yup, understand the SLS set up now , was missing the fact that trailing becomes leading when reversing :oops:
