at about sixty mph I start noticing a slight shaking then at about seventy to seventy five mph the shaking is very bad sometimes. sometimes will not even notice any shaking at all. What I notice is the front right wheel and the left rear wheel get slightly tight. then i need to bleed the brakes front right and left rear and it pours some brake fluid out. I have no idea if this is related with the van shaking. thanks for your replies.

with the brakes off check to see if fluid squirts out or barely comes out. if it squirts then it may be a bad brake hose or caliper is freezing up . then get tires checked for balance. could be an axle shaft, but it may be more of a tire problem.

When the wheels are tight the brake fluid would squirt out.
otherwise will not bleed out.

Caliper pins cleaned and lubed with silicon lubricant.

After going for a ten minute ride the right front side and rear left side brakes get locked.
if i loosen the bleeder, fluid would squirt out.
i have gone through a couple of brake pads and it is just the front and rear left that are worn out to the metal.

have a mechanic check for a frozen caliper or it is hanging up and not moving in brackets. they should slide in brackets. rust can cause this also.
