Not PT but disk brake problems.....

[Olav]

My dd Chevy Tahoe 2002 have a issue with the rear brakes. I changed all 4 rotors and pads, handbrake linings and backing plates. Replaced the long brake line on top of frame to rear. Bleed the brakes. Guide pins on calipers is lubricated and calipers are moving free . Now the rear brakes is not loosing pressure when I drive. They are hot and almost block the wheels ? This happens after 5 min driving.
I have a few teories regarding this.

1: Rear brake hose is not letting fluid return. Collapsed inside ? I had same issue a few years ago on a Caprice -90 when i mixed DOT 5.1 and DOT 4 brake fluid. Why is the brake hose collapsing ?

2: When I put every thing together there was hardly enough clearance between rotor an pads to mount together. Is the rotor getting so hot it grows wider and starts to brake ?


After 5 min the wheels are free but i don't know if the rotor gets colder or fluids returns ?



Any comments ?
