Question about 1983 Toyota Land Cruiser

1 Answer

Toyota hj 60 (diesel) vacuum hose if pulled off the vacuum brake drum, I can get it to **** onto my hand, but not getting a vacuum in the drum itself.Diaphram seems to have no tears. Although, the pin which is driven into thte master cylender passes through a loose ? seal in the outer case of the vacuum drum. IE, I can't imagine a vacume being contained in the outer half of the drum, the loose seal would let it out! Is this seal critical for operation, if not where should i look next? regards Richard

Do you have the check valve instaled the right way ? It only allows the vacuum to flow one way.

Vacuum pump hoses


if the hose is about 1/2 inch and about afoot long and has oil inside of it probably is an oil return line back to the sump. If it is clean inside it will go to a item requiring vacuum like a governor or a brake booster.

1994 toyota 4runner no vacum to brake powerbooster


The check-valve could be bad or the vacuum hose from the manifold could be blocked.Did you pull the hose out of the booster and start the engine to see if vacuum is there? How did you know there's no vacuum?Some times the check-valve is in the hose and some times it is in the booster.

You no longer have vacuum assistence. The brake master cylinder is mounted on the brake booster which uses vacuum generated by the engine to "help" you push the brake pedal. On diesel engines there is normally a vacuum pump on the rear of the alternator which generates this vacuum. On petrol engines the vacuum is generated by the engine itself. Follow the pipe from the booster to the inlet manifold or alternator(diesel) and check for leaks along the whole length and at the joints. Replace the pipe if leaking. If no leaks are found the booster needs replacing. If you have a diesel engine, check the operation of the vacuum pump first before replacing the booster. Make sure the alternator is turning(belt in place) at idle. Disconnect the pipe at the rear of the alternator and hold a piece of paper over the pump opening to check operation. Do not use your hand as this will result in injury even with the engine at idle. Replacing the booster will see you upside down under the dashboard swearing, pleading and begging because that's where the bolts are that hold the booster in place. The master cylinder needs to be removed from the booster before the booster can be pulled from the engine bay.

Sounds like there is a fault with the vacuum pump not generating enough vacuum for the brake booster assist, or a leaking vacuum hose. Try pinching off all the vacuum hoses to see if the problem goes away. Could also be a leak in the brake vacuum booster itself

Broken lug bolt


Easy. Take wheel and tire off, and remove the brake drum, if it has drum brakes. With a hammer, hit the broken stud until it pops out. Slide the new stud into the hole, and, using some thick washers, screw the lugnut onto the new stud, over the washers. Tighten it until the stud is pulled all of the way in. Easier done with an air wrench, however.
