How hard would it be to........

Swap in Non-abs brake system in place of my abs system? What all would need swapped over? I have a doner rover in mind, just need to know if I should get that or a new abs pump?

As far as I know, you'll need a new Master cylinder, as the ABS one I believe is all integrated into the master cylinder assembly. Plus the non-ABS master cylinder requires the use of a brake booster. You may need to replace the push rod for the master cylinder, not totally sure. Also the replacement of valves, I am not sure totally if you have to run new lines, doubt it, but maybe.

Just from what I mentioned it seems to be A LOT of work, not worth the hassle. Why would you wanna replace the ABS components with non-ABS ones? Is it that fact that your ABS system is not working at all? If so, why not just repair the problem?

Just saying, if you wanted to, it will cost a pretty penny, regardless whether you have doner parts from a similar rover, IMHO. But then again probably not as much as I think. It all depends. But overall it is a tough task it looks like.

You should also check your local laws to see if it is legal. Here in Oz it is illegal to do it.

Pat, are you studying to become a lawyer, or a politician?

JUst kidding you.

I do agree, why not just fix it?

Well, when I bought the rover, All of the abs sensors were unplugged. I'm not sure of the reason. I drove it for about 100 miles and the abs pump took a poop. I pulled the pump off and dismantled it. The little metal pins were seized up inside of the cyl, so I took a small file to loosen them up. Now, the pump makes a whining noise, and I'm affraid that it's going to need replaced. The pumps I find used are around $200. I can get a whole 88 Range Rover for $100. *Minus some body panels. I was thinking that I could solve the problem by swapping the vacuum booster and master cyl over, but I noticed that my calipers have 2 brake lines in each of them. What's up w/ that? I just wasn't sure how much money I'd have wrapped up in fixing my abs system vs. replacing w/ non-abs. Thank you for your time and advise.

The two brake lines per front caliper is due to the fact that each front caliper houses 4 pistons, and that there is one brake line per two pistons on one front caliper. Now, on that 88 RRC you mentioned, does it too have the 4 piston calipers? I doubt it might, but not sure.

I am pretty sure that after getting a new pump, you'll have the problem solved, but it's one of those deals where another person would have to look at it to be sure, not saying necessarily it had to be the dealership. But, the main thing is, does the truck still stop? Is the pedal nice and firm? If all of that checks out, just keep it simple, and replaced only what's needed, IMHO. All of that being said jogged my memory, and I knew guy that awhile back, converted his Dodge Half-Ton from non-ABS, to ABS system, it was a pain in the ass he said, not necessarily worth it. Although with his ABS working he was able to stop-steer his way out of hitting a tree in the road so he tells me.

And Terry, that's funny.

True true, That electric abs pump is just foreign to me, and seems "fragile" I dunno, I guess if it lasted 123k miles, it's not a bad idea. Just the combination of everything going on worrys me. I do have brakes, and the pedal is hard, but before the pump quit pumping, it made the noise that it makes now. I got all of the needles moving freely, I don't understand what the problem is. The accumulator ball, should this be replaced at the same time as the pump? The pump runs quite often. I'm really just trying to understand this thing. I'm a gm mechanic, and this range rover is like a totally different kind of machine. I do understand some of the engineering behind parts though.

Yeah, I too am new to the fundamentals of Land Rover engineering, and the brake system on a Rover, especially ABS systems, are quite complex. Also the bleeding sequence is more time consuming, but pretty straight forward.

As for that accumulator ball, it doesn't need to be replaced the same time as the pump, at least not what I was told in school. My instructor had worked on similar systems and I asked if I replace one thing, is there usually something else that needs replacing along with it, and he said not really. Basically don't need to replace it if it's not broken.
