I am having trouble getting to rear brake lines to remove and replace. The issue I am having is that the lines go into the frame in front of rear dif. which is behind the body's back seat. there is very little room to get a line wrench to turn. On the otherside of the same location the line is rubber down to the rear dif. then metal line splits to each break. what is the best way to remove one line from the frame without breaking the other? does the junktion box come out?

jack up car, fit safety jacks at each side of frame well in front of rear wheels, remove tail shaft , place floor jack under rear axle housing and jack up , but not lifting off safety jacks.remove brake lines, remove rear shocks, remove drag links ect from chassis frame, lower and remove jack, wheel out rear axle.
Hello, do you have brake in the front or in the back or both? Have you bled the
air out of the braking system? You need to think this through instead of
RR--remove and replace. The hydraulic brake are the most reliable system that
the brake shoes or pads could be down to the metal and it would still stop the
vehicle. You lose a brake line or brakes on one wheel, and it will still stop
the vehicle with two wheel cylinder or pads working. The brake system is
diagonal that is; left front/right rear and right front/left rear. Therefore, if
the vehicle loses any one braking system the other will work.
Now, on your Toyota Truck there is load compensator valve hook to the frame
with the two rear wheel line going into this valve. The a lever the attached to
the rear differential. The way it suppose to work is when a load in placed in
the bed of the truck. The load dynamic will position the differential by the
load pushing down on the bed. This causes the load lever arm to change position
and slightly closing the valve; in turn, limits the brake pressure on the rear
wheels.
I don't know why Toyota Motors installed this load compensator valve. It more
trouble than what it worth. I have removed these load valves, and took it apart,
and plug the valve piston hole with a brass plug. This lets the brake pressure
flow evenly through out the braking system.
Remember, you need to bleed the braking system of air and I mean all the air
bubbles for the braking system could operate appropriately to manufacture
specification. GB...stewbison
It sounds as though where the rear brake lines meet up with the master cylinder; there is probably a piece of dirt in the lines that could be blocking any fluid from getting in. To test this, I would remove the brake lines from the master cylinder and then remove the master cylinder. Once done, have the master cylinder cleaned inside out. This will remove the dirt particles that are clogging your lines.
well your master cylinder would be most peoples guess however i am over qualified in hydraulic and air break systems you need to replace your equalizer valve its on the frame on the drivers side of the vehicle
Brake fluid is highly corrosive. If you can't get the line loose on the frame side then I would suggest replacing the hard line as well coming from the master cylinder. Or if you have a flaring tool you could cut the hard line just behind the rubber and put a new fitting on it. Pretty easy if you have the tool. Essentially you will wind up kinking or breaking the hard line anyway if the fitting won't come loose easy.
you would have to remove the gas tank,,, i usually just fish a new line in there along side the old and splice it in toward the front, and at the rear brake line T ,,this is the easiest way -jeff
