I'm going to be replacing my brake lines with these kevlar braided stainless steel brake hoses from EGR Performance Brakes. I'm also going to replace my pre-bent rear hard line tube while i'm at it.

When you go to order, they sell different kits depending on if you have 2 wheel or 4 wheel anit-lock brake system. I checked the Chrysler service manual, and our trucks did indeed come with either a 2 wheel system, called RWAL in the service manual (Rear Wheel Anti Lock), or a 4 wheel system called ABS in the service manual (All-wheel Anti-lock Brake system).

My question is, how do I know which I have?

 

My build sheet has this on it:

BGJS - Pwr Disc/Drum Rr Anti-Lock Brakes

I think this means I have RWAL.

 

I bought the Russel Stainless Steel Braided lines. I'm going to install them whenever I replace my track bar and front brakes.

 

If you don't have ABS, the you WILL have RWAL. Its either you have one or the other. however, idk where to look to see if you have ABS, since I have RWAL. You might check the brake pedal itself, usually it says "4-wheel ABS" or something similar on the rubber pedal cover.

 

If you have 4 wheel anti-lock there will a wire to a sensor at each front wheel.

 

There should be an extra set of wiring coming off of the pcm if you have 4 wheel ABS. More than likely its rear wheel abs.
All of these trucks came standard with rear wheel ABS as well.

 

check the relays. If you have a relay where the ABS relay goes, then you have ABS 4W

 

+1 on the wires coming from the hubs, the extra relay, and PCM wiring. My guess is you'll have rear wheel only.
