OBP peddal box, fronts locking up
Hi
As it says above, im running an OBP pedal box, and all is working fine, although the front brakes do lock up a bit quicker than I would like
ive never really set the system up, just got it up and running, and tweaked it from there
so to reduce the locking up, what do I do ??

you can fit stickier tyres....
or alter the brakes so a bit more effort goes to the rears. Either by altering teh bar (if that is possible) or changing master cylinders. However,
fronts locking up first is very very preferable to the rears .

The balance bearing needs to be screwed so it is closer to the cylinder that operates the front brakes, try only one turn at a time.
Test for rear locking at low speed on a well surfaced clean dry road. Front locking is more likely to occur in the wet.
Balance bars only work well if the bar is set not too far away from the centre, the adjustment becomes less sensitive. If you cannot get enough
adjustment then you need to consider changing one of master cylinders or rear wheel cylinders.
The balance bar Trunnions need a sufficient side clearance to allow the bar to "wobble" enough for the balance bar to work properly.

Think that should be the other way to reduce front braking and increase rear.
I'd adjust to the rear one turn at a time untill you lock the rears (find a VERY quiet road to test) then turn it back to the fronts by one
turn. You DON'T want the rears locking first.
If once you've adjusted the balance, you find it still locks the fronts sooner and withless effort than you like, then you need either bigger
master cylinders, smaller calipers, less pedal leverage, stickier tyres or a weaker leg... Though too much braking power isn't something people
complain of often.

ive screwed the back brake bar one turn to make it closer to the pivot point, and the brakes are so much better

And thanks, for the help
