Check the parking brake shoes maybe? If you don't normally use the parking brake and the shop you took it to did it might have messed them up. Those are notorious for deciding their life goal is to become an axle destroying frag grenade at inopportune moments.

 

Im new to the titan platform but, as far as i know titan should be running on ebrake shoes. So if it grind when you go in reverse most of the times it means the shoe is wearing unevenly, spring is loose or the shoe is popping out.

 

You're better off just pulling them off and not replacing them. They are a flawed system that really doesn't hold your truck in place even when they are in working order.

 

I don't know why they would pull the e brakes assy, but if they did and reversed the shoes on re-assy, that could be an issue. There is a front shoe and a back shoe.

 

I pulled mine, they were working 100% as intended and would not hold the truck in place for chit. Like stated above, its a poor design that doesn't even work.

I could set my e-brake, and put it in gear and it would still roll. Worthless.

 

Mine will hold until I get about 1200-1500rpm on the motor. It's not a bad design. The OEM shoes are prone to delamination if you get them hot, but the design is sound. I have the same design on three different vehicles here in my driveway - my T, wife's Expedition, and my son's 2000 F150. Just did a rebuild on the F150's e-brake.

What I will suggest is to be sure the e-brake shoes are properly adjusted after reassembly. These things aren't self-adjusting like drum brakes of old.

 

My brakes hold fine when applied. I only apply them when I'm parked with my boat trailer, never use them other than that.

Rather be fishing

 

I'll chime in with the others....when I replaced mine I used NAPA shoes, the most attention had to be getting the manual adjusters on both sides right. Without enough tension they creep, too much and the shoe lining will heat up when driving. I used an infrared thermometer to check the drum temp after a few mile round trip to get them right after adjustments (3 total). PIA!

Mine hold fine without creep, but I learned early on to keep the brake foot pedal applied fully while setting the ebrake before shifting into park. I have no explanation other than perhaps it's my truck's personality.

 

+1 on check your e-brake shoes

Mine hold fine...even on very steep grades... ...now that I replaced the shoes, cleaned the drums well, and properly adjusted them.

BUT

When I got the truck home the day I bought it...the e-brake did not work at all, and upon my inspection of the rear brakes, the lining from the passenger side lower shoe was GONE... metal on metal in the drum... That'd make a grinding noise... for sure.

They are way too easy to get into for you not to look... its a 20 minute job
