Rear Brakes

Post by SilverRide98 » Mon 11 Nov , 2013 2:31 pm

Today I ran the H1 around to get everything moving and heard a strange noise from the rear. When I looked under the truck, the left rear rotor on one side is half way gone. I know I need to change both of them now, but does anyone know why only half would wear down? The right rear looks fine and I have adjusted my E-brake to hold the truck from moving on even ground and little throttle. Is it possibly a struck cable or mech on the parking brake?

You must mean the rear pad. If the pads are not loose in the rotors they can hang up and wear unevenly. I used to take a screwdriver and a light hammer and tap the metal 'ears' that stick out beyond the caliper to break the pads free. They will jiggle around a bit. Make sure that your guide pins are clean.

Chuck,
Yes, they are the rear pads and would you suggest using and type of lube on the pins?

You didn't read the article. <g>
Pull the yoke out of the caliper. Clean up the caliper and more importantly the 2 caliper guide pins on the yoke. If these pins aren't free to move the pads will wear unevenly. I first spray solvent or WD40 on them and wipe them off. I then take a single edge razor blade and scrape off the remainder of the buildup. If there is still some corrosion I use some steel wool or fine 600-800 metal oxide sand paper to clean them off. If the pins are really bad get some new ones. Then lubricate the pins with the green Permatex caliper lube.

Sorry Chuck I saw the caliper lube, I was thinking that was the noise stuff for the backing. Also, when I get the new rotors in tomorrow I will see if the part numbers are the same from Autozone, they where only 39.99 each. I ordered the duralast pads too, last time they came in a padded box and each pad was protected by foam. Thanks

The brake pads are Duralast MKD 1025 and the rotors are Duralast 5701. Sad thing about these both, are made in China (uhhhgggggg).
