It seems the resididual valves are behind a brass cone installed in the exit fitting, where you screw in your brake line. They say to pull it out with a screw extractor, remove it, and reinstall the cone.
thanks. I would imagine not removing it would only lead to premature wear of the brake components... there is a big difference between 2lbs and 10lbs of residual pressure.
On my fj40 MC, the residual valves could easily be removed by unscrewing a nut that held them in place. I am looking to...
@Green Bean, What MC did you install?
Removing the spacer would give me extra room in the engine compartment, but the length of the rod would be too long. I would have to see if it would give me enough adjustment on the pedal side. I have not yet had time test fit it all.
Does anyone know where residual valves are located? @archie73, if your brakes are singing, I would imagine your 10lb residual drum valve is still installed? Wouldn't you need to remove it? I was originally running my 74 MC with the front residual valve removed completely, it stopped great.
My 1974 OEM booster failed a few years ago and have not had time to deal with it. I started rebuilding the 74 booster that had brake fluid leak into it. I tore it down, repainted, and reassembled it, but was unable to get some of the external gaskets to finish the job.
Finally getting back to...
I have a 74 FJ40. I have disks in front, and drums in rear. I just ordered a new booster to replace the OEM that I rebuilt, but was missing one seal that I could not find, so decided to upgrade to the later dual diaphragm booster.
I have a 93 toyota pickup Master cylinder and was wondering if...
I rebuilt the 74 booster myself (or really should say tore it down, cleaned it and reassembled it), but i need one part and could not find it (rear seal). so I shelved that booster. And since it is inferior to the later boosters, i thought i would upgrade. I will try to get some pictures later...
I found a booster from a 1993 mini truck and thought it would bolt up to my 1974 fj40. It is hitting the parking brake cable and housing? Do I need to do any modifications to install this booster?
He is saying i need a proportioning valve to run disks on the front with a 1974 MC or the rear brakes may lock up. I have been running my former MC for years without problem on the disks. I just removed the valve from the front circuit. never had problem with brakes locking up.
