I've owned a 92 and now a 99 4Runner. Both vehicles have brakes that freeze at very cold temps i.e.: minus 26C. No matter how hard you press on the pedal, NO BRAKES !!!! Pump them a few times and it is as if something releases and the pedal will go down as normal and brakes work. Only happens first thing in the morning and only after the vehicle has sat outside in frigid cold temps. Fluid has been changed yet problem still happens. I think the booster is freezing and I think Toyota is aware of the problem and will not address it. Anyone experience this??
