1990 odessey rv. complete brakes rebuild, shoes, wheel

Customer Question

1990 odessey rv. complete brakes rebuild, shoes, wheel cylinders, axle brake lines, fro nt pads. brakes all have been bled, pedal is solid, problem is front brakes lockup under hard braking, and immediately release when brkes are released. I ad justed proportioning valve to no avail. vehicle is unsafe to drive, all tires set at 50psi front and rear, and air bags on rear axle set at 30psi. also upon stopping if I pull up on the emergency brake the rear brakes do try to slow the vehicle. The brake do feel normal up until the front wheels lock up and I have put about a 1000 miles on them scince doing the brakes. any ideas ? thanks dave, a retired auto truck mechanic. ***@******.***
