Denis, has anyone done work to the cars master cylinder recently, if so the adjustment rod at master cylinder may be adjusted incorrectly and when hot the brakes fluid etc.. The adjustment rod expand s , locks up back brakes and gives a real high brake pedal

We do not know what maintenance has been performed in recent history. Was the fluid flushed? if so when? hoses changed? Condition of brake fluid in reservoir?
Many of these issues can be prevented with regular consistent maintenance. If not you may assume debris blocking various areas causing pressure, most commonly in the G valve

Hi Denis got your pm, you might confirm whether the master cylinder had work done recently, so we might debate symptoms here thanks}

Blocked hoses act like one way valves keeping brakes on.
