Brake bias

[MattJackson82]

I’ve fiited my 182 with a cup master cylinder new internal brake pipes with a bias control valve, I’m using HC carbon front discs & DS1.11 pads, standard rear discs & pads, I found last week when out on track in the wet I can’t get enough bias to the rear, with control all the way to rear the front still kept locking & the rears are hardly getting warm, any ideas to send more to the rear please?

I'd be looking at the bias valve, what brand is it?

It’s this one in picture James OBP motorsport one.

Could well be that that's not working.

The Tilton level type valves are generally the go to ones.

I would look at running an uprated pad in the rear also, I use PBS pads in the rear.

Yeah my first thing is going to be updated rear pads, I had PBS prorace fronts previously & it wasn’t as bad as it is with DS1.11’s I think they are over powering the rear brakes, it does work to an extent, if you jack up the rear wheels & get someone to press the pedal they are solid with full rear bias but if you turn it fully the other way the rear are then only binding with the pedal pressed.

 

[JamesBryan]

Try some higher friction coefficient pads in the rear then and see how you get on.

Id buy a proper bias valve like tilton or ap racing.
