SIr, I have a land cruiser 1985 BJ74, it has a brake problem, i have to press brake pedal with a reasonable of force to get it work, further my suv slightly turns to either left or right on braking. Steering has tilt problem same as if it needs an alignment. Engine has started giving smoke. Please help.

your problem is most likely the brake assist pump or controler

I would tighten till hard then one more nip,should not need to be tight as because you have a gasket inbetween.

Start the engine, fill up full the brake fluid reservoir, and let someone press the brake pedal down to the floor for 3 times,, bleed the bleeder screw behind the tire.. position yourself closed to back plate of drum or caliper for easy bleeding work. when the bleeding screws is loosed brake fluid leaks with a bubbles. then close it again and tell the guy in the pedal brake to press it again until a hard press is felt and bleed the bleeder screw again, stop only the process when there is a hard pressing already on the brake pedal which is the brake system is now working properly.

The problem is not in the transmission , check air filter element , fuel pump pressure and filter , check transmission fluid for viscocity [email protected]

Could be a number of things,you have a leaky master cylinder or leaky slave cylinder....'s or air in the lines or no brake fluid?

yes all brake boosters have to have a vacuum line

the brake pedal you depress with your foot has a plunger style switch that activates the brake lights. that switch is at fault if the brake lights do not operate upon pressing the pedal

check to see if you have a switch on the top of the brake pedal . it may require an ohm meter to see if you have continuity through the switch when the brake pedal is depressed

no easy one but some main wire under your dash is hook wrong did u have any thing new fit in
