My 1991 1500 2-wheel drive silverado front driver brake grabs the most.HOW DO I FIX IT?

I came down a hill when i reached bottom my brakes were glazing! I got back to where i was going and checked the temperature on all wheels the driver front was 340degrees,the P.S. was 180degrees,both rear was 82 degrees. i have already changed the flex brake line on the front .P.S.,that cured my brake problem about 8mths ago.My 1991 1500 2-wheel drive silverado front driver brake grabs the most.HOW DO I FIX IT?Sounds like you need to replace your brake calipers and put on a new set of raybestos brake pads. Same thing happened on my 88 GMC 2500. An easy fix if you know how to work on brakes.
