Couldn't figure out how to embed it. This weekend's race, took first. New Maddat rear springs are really good. They're a bit too tall for my taste, but the results speak for themselves. I also ran a different rear tire. Nankang started making a good 13 inch tire and the price was too good not to try. Really happy with them.

Anyone that has these installed on a ute, how much did you cut from the front perch and did you reinforce if after cutting?

Does anyone know the spring rate? I've emailed them and no answer. Not sure if they're still in business, but the site looks like they are.

Are there any similar springs offered by other companies that people have had good luck with? They'll be installed in a Sunny Truck with 20 valve 4AG that gets autocrossed. I currently have Japanese (Matsuoka) leaves and one side sagged to the point that I temporarily fixed it by making a longer rear shackle. I don't carry anything but extra wheels and tires to the track, so load rating is not important to me.

Thanks!

No, it was solid mounted. Looks like there's room inside it for something to slide back and forth. I got some calipers from a friend and swapped them at lunch today. I must have buggered something on the rebuild because they work great. Now I just need to work out the e-brake.

So I removed the valve, and no change, so that's not it. I probably goofed rebuilding them somehow... I'll report back when I figure it out.

So I shouldn't remove that, I'm assuming? I may bypass it tonight anyway, just to see. There's not enough wheel travel on my truck for that thing to work in the first place.

The front circuit doesn't go to this valve.

@ ddgonz - So is the disc-front brake valve pretty much the same thing as the residual pressure check valve, and needs to be removed?

@ dodgeman - The new master cylinder is from an S14 Silvia, same car I got the front and rear calipers and rotors from. On a side note, it bolted right up to the late Sunny booster and has the same plunger depth.

Yeah I originally thought it was some kind of load proportioning valve, but it's not attached to the suspension any where. I never gave it much thought until now.

I thought I just finished with a rear disc conversion on my Sunny truck (minus the emergency brake cables) but the rear discs are dragging after bleeding the brakes. All calipers, rotors, and master cylinder came from a non-turbo S14 Silvia. There is some sort of valve in the rear line before it reaches the rear diff and splits off. It's near the back wall of the cab, inboard of the frame rail under the bed. This truck came with front discs from the factory (1991). Is that residual valve that makes the drums work correctly because I thought that was incorporated in the master cylinder.
