    Default brake bias, rears locking before front

    car - rt142

    motor - 22re (irs and rear disk)

    use - daily ish

    problem - rears lock before fronts

    occurs/started when - since i got it, still dose it with ra65 calipers and rotors on front

    personal situation - check under rear for proportional valve like hiluxs have that is connected to rear suspension in case it was stuck but dose not even have one, so do the have a proportional valve in the master cylinder that may be stuck or blocked or out of adjustment or is it just the difference of the front caliper pistons to the rear caliper pistons that change the proportion from factory? and defiantly is using rears more than fronts under normal conditions too, even only after driving around for a few weeks brake dust it on the rear rims but not front

    ever thought that the rear lock up first as they have less weight/pressure forcing them to the ground?

    well yeah thats what bias is for to overcome the fact that there is less weight on the rear

    if it was discs all round from the factory, the valve will be on the fire wall ,hiluxes only use the valve at the back for heavy weights ,etc the more weight in the back the more it pushes down on the valve
