Finally got the RB front and rear 400/380 big brake kits installed. These brakes are awesome! The difference between these and the stock (standard) brakes is night and day. They have great pedal feel, they modulate easily, the front/rear balance is right on, and you can feel a nice, solid grab even when you stop moderately. When I went to bed the pads, I thought the truck was going to stand on its nose. The RB parts installed easily. The rear dust shields were not compatible, but I didn't need those anyway. The only big problem was that the factory had grossly overtightened the front hoses at the chassis end and crushed the threads at the end if the hose. Removing the hoses chewed up the threads along the entire length of the fitting on the hard line. Chasing out the threads on the fittings was not easy. However, even with that, I am very happy to have the stainless steel lines that were included with the kit. Not only do these brakes work, they look mahvelous! They don't look at all lost inside those big wheels. And yes, I know that black wheels are the way to go these days, but I'm old and I still like my wheels shiny.
I want to say THANK YOU! to Unbroken for recommending RB and the BC Forged 22 inch wheels and all the other things he has recommended and posted about. And thanks also to all the others who have found good stuff and posted it along with installation tips (really helpful!). Building up this truck over the past two years has been a whole lot easier and more fun because of all of you.
