all 4 would imply a master cylinder problem. Is it single or twin? Do you have a spring to ensure that the pedal returns fully?

I've just had a similar problem on my Cobra but it only affected the front brakes. If you let out fluid through a bleed nipple the brakes are
ok.
Firstly check that you have left enough "space" in your reservoir for the fluid to "expand" once the brakes are hot.
If that is all ok then it's a problem with the master cylinder - had mine out 3-4 times and changed/checked te sealsbut nothing would sort it. I
ended up replacing the master cylinder and everything is ok now ( I think the bore was a little scored)

I would suggest to look if the mastercilinder comes into the orginal rest position. Probably not. So the fuild can't flow back which causes
these problems.

When they lock up, try hooking your toe under the pedal and pulling it back up. If the brakes free off, it supports the "not returning to the
ready position" theory suggested earlier.

Exactly my thoughts - you might need to install a return spring to allow fluid to move around correctly. It might be binding pivot linkages or just
need bedding in.
