Brake thingie under 1988 Samurai

Hi Zuks;

I have a 1988 Samurai. There is a thing-a-ma-jig attached underneath to the frame on the passenger side
across from my rear driveshaft with brake lines leading in and out. It is leaking brake fluid.
Question #1-What is this unit properly called?
Question #2-Can it be repaired or should it be replaced?
Question #3-Can a rebuilt unit be purchased or only new ones?
Thanx for any and all info.
Lee

Hi Lee
I think it is a brake pressure regulator. My old Zuk had one that was connected to the axle and increased the brake line pressure in the rear brakes when the vehicle is loaded. However the Zuks in England seem to have many different types fitted. I would suggest you need a new one as they corrode and are difficult to re-seal.

Re: Brake thingie under 1988 Samurai

its called a praportioning valve. the 88 is the year they changed to 1 line to the rear axle. so you will have to get one from a 88 or newer zuk. the parts stores around here don't carry them, and the dealer wants 110 bucks. i have an 87 with the same prob (2 brakelines to axle though.) i can't find a junkyard with an 87 or older zuk. sooo.....if anyone has one im lookin for one also. if not i am gonna get an aftermarket one and have to change all the ends on the factory lines.

build it, break it, then build it better.

Re: Brake thingie under 1988 Samurai

Turning to page 19-41 in the Good Book ('88 Samurai Service manual) I see a diagram that calls your thingie a P&B valve.

It should have three lines coming from it, Two going forward, one going to the Rear Axle.

On it you will find three bolts. Two of them hold the unit on the frame. The third "bolt" is actually a bleeder plug.

If the fluid appears around it, check to see if it is partially open. If so, tighten it down & see if that will stop the leak. If it did, then someone probably forgot to tighten it down real good the last time the brakes were serviced. If not, it's time to find a new one.

I didn't see it in his parts list but he may have it...
