from the email most of you probably got this morn..

URGENT, POTENTIAL BRAKE PROBLEMS
If anyone who is racing at Paeroa is running two brake master cylinders operated by a single pedal please contact Ian Staples asap.

He will be at Paeroa checking these for correct operation but you will need to check them and make any changes before.
Please contact me and I will explain the set up.

I guess even if not going to Paeroa it will pay to look at the brake setup and ensure it is operating as expected..

Will photo/pull ours apart and then see whats up with ours - we think its the right setup as when I lost one master cylinder (siezed up) the other one still operated.. was just a bit harder to stop!

this check is a result of Scrivy and Bob's Wanganui dramas which may be different.
they had total failure of one of their lines which would've produced no back pressure on that master cylinder, if yours had seized it to my thinking would've had back pressure so the bias would've then moved to the other cylinder so maybe you want to have a lookseee again and see whether it would work in their situation

Yip, fair point. Will be looking at mine.

My master cyl had siezed at the bottom of its travel.. so kind of like all the fluid going?

Anyway, agip bikes setup is a bit tired and worn so will be looking at it among other things. Head up to ChCh work on it for a good few days next week.

The setup i have allows for total failiure of either masteer cylinder and the brakes.still work. The balance bar has a fixed centre pivot point, so either master cylinder could fall off and i would still have a fulcrum for the bar to pivot on.

Nice, ol' Phil recons his dads rally/targa mini's have a cool setup and can't (shouldn't) fail either. Will have a geez at our options next week..

So whos keen to be a passenger for a novice at the national rounds at hampton and taupo including the fridays before hand?

My swinger that will normally be on doesn't want to fork out for a race licence to compete in 2 rounds so need to find someone else to jump on, would prefer someone with experince as i have no idea what i'm doing haha

[sidecar bob]

Our brakes did exactly what they were designed to do in the event of one line failing, not work altogether. There were no further faults in the system & basically, it was like one kid jumping off the see saw when he is at the bottom, the other one goes straight to the floor.
The suggested fix needs to be worked through a little more thoroughly & Nev I & others are working on what is the best solution.
Im all for something being done, as long as its the right thing & well thought out.
Gotta take your hat of to Ian, he is seriously into our safety.

Warwick might be keen..

wheres Kick at.

Our bias adjuster is being fitted with a limit plate, to stop it piloting around so far that the other master still has pressure no matter what.

We've also read the rule to mean, the backup brake has to work completely independent, and fitted a real serious hand operated front brake. Brembo for the win!

I didn't think that rule was around anymore.. most bikes don't have a back up brake.

Agip bike has a 4 pot caliper and chunky AP master cyl running the hand brake.. Althought we took it off. Must re-fit them.. When it works it should be able to lock the front up pretty easy. Hopefully it was the brake dragging that was causing the fluid to boil and lack of pressure for the hand brake.

The rule that Spyda (I think) quoted earlier in this very thread, still reads that a second system is required.

I would argue the rule to the contrary, but it suits a purpose I have in mind where the stand alone front system has an advantage for me.

We are all motivated by selfishness at the end of the day, after all.

Oh yea.. Can't be bothered trawling back through the thread..

I guess its not an enforced rule at the mo.

That is not the way to look at any race rules I'm afraid.

haha.. tell that to all the bikes who don't have a hand brake.. we have one already.

There's an argument to be made, that if the bias adjuster cannot simply go down the path of least resistance and not actuate the other master, then it is "it's own system".

But it is still worked from the same lever, so it is not a strong argument.
