twin master cylinders and IVA?
I know the sierra master cylinder has a low fluid warning switch as standard but is it needed for IVA?
Is this warning system needed when people use twin master cylinders with a balance bar and if it's needed how have people got round it?

You can use twin cylinders but you need to use reservoirs with the low fluid doodah from folk like car builders solutions. I seem to remember that the bias bar needs to be locked so its no longer adjustable, yep it kinda makes a mockery of it but that's IVA for you....I might be wrong though as it's been awhile

I know the balance bar needs to be lockable just was'nt sure about the low fluid warning system. I'm going to play with some possible new pedal boxes, with my knees and ankles being the way they are the standard floor mounted set up will not work for me. Might try a hung set or possibly try and rejig the book design. Thanks for heads up about CBS.

Yes you do Phil, it's a very important part of the test. You need to have a way of testing its operation, sierra's have a push button in the top of the filler cap that will activate the switch when pressed. Also you need a way of checking that the bulb is working in the warning light, reason why the handbrake light is also the low brake fluid warning light or you can have a separate switch on the dash somewhere that will activate the light.

Yeah hanging pedals work best for folk with big feet and also may be able to get more room by taking them further into the engine bay...have a butchers at a Caterham to see what i mean about that bit

thanks for that guys, I don't have big feet I just don't have much movment in my ankles and knees due to the dreaded Arthur, I have to drive by moving my whole leg instead of flexing my ankle.

i understod that all brake fluid res's need low fluid warning and ballance bars need to be locked and renderd unajustable (eg welded) so a bit of a waste of time fitting one until after iva realy
im looking for a solution to the peddel box would be good if we could find out in a doner option could be found i dont mind what way up the peddels go but i do have size 10's |

Quote:
"A very common mistake is to lock the position of the balance bar by tightening the locknuts directly on the clevises effectively locking their floating action. THIS IS INCORRECT AND DANGEROUS. If the balance bar is to be locked after adjustment, all that is necessary is a single locknut tightened against a sliding sleeve to lock the thread against one pivot pin, thus allowing the clevises to swivel freely and maintain alignment with the master cylinder push rods and pistons. The sleeve must have a wall thickness thin enough to allow clearance in the clevis. Also, to maintain sufficient braking pressure on one cylinder should the other fail completely you must minimise the clearance between the two clevises and the steel tube in the brake pedal so that the balance bar rocking movement is limited to the angle necessary for the desired front to back balance, and no more. NOTE: IVA compliance requires that, after the brake bias has been set to an appropriate and acceptable ratio, the adjustment be rendered immovable. We understand that drilling and pinning is no longer acceptable and that the locking nut must now be welded to the threaded shaft." |
