    Have you checked the main fuse in the engine bay fuse box? This should blow to protect the electrics in the case of a major short.

Are you sure you checked all of the fusible links, that is the most likely cause of your problem. They will usually look burnt when they go out but not always, sometimes the burnt place will be on the bottom side of the wire and not easily seen. Do a continuity check on all of them but be sure to disconnect the negative battery cable before you do.

92 4runner everything been changed. Brakes, booster, line to booster. Still the same brakes are every hard to push. Can't figure it out any idea. .

Usually theres a plastic valve mounted on the booster thats connected to a vacuum source. Remove it from booster(they usually just pull out) & hose, then suck& blow on one end. Air should pass only one way. If it passes both ways the valve should be replaced. Check to c if hose holds vacuum by placing thumb on hose end to feel for suction (motor running) & to listen for hissing. Replace hose if suction is low &or hisses. Could be a vacuum leak elsewhere in wich case performance would suffer & idle would be eradical.

Fuse keeps blowing.even after i replaced the cig. Lighter why

Main cause could be something stuck in the lighter socket. Sometimes, the ends of the car charger for a cell phone of GPS will separate, leaving the end in the socket itself. Placing the cigarette lighter back int he socket while there's something already in the socket will cause you to blow a fuse.

Factory stereo will not power up found booster fuse blown and everytime its replace it blows right away

whatever you do don't put a bigger fuse in because it'll just cause more problems. it's either that there's a damaged or burnt wire or something inside the stereo has gone. so just check the wires and if they're alright it'd be easier and cheaper to just replace the stereo instead of trying to find someone who'll fix it.

Removing the rear brake shoes

Some of it went into the slaves as the shoe material was worn away.

Brakes are pretty important to have and to have work correctly. If you are not absolutely certain what you are doing and how it is to be done properly, please don't do it. Have this repair done by a professional.

Need Break Booster Replaced

The brake booster/ naster cylinder is located on the firewall on the drivers side of the vehicle. The master cylinder has a resivour (sp) which has a cap and holds brake fluid. The brake booster is right behind that, the master cylinder is bolted right to the booster. The booster looks like a big circle about 10 to 12 inches round and usually 4 to 6 inches thick. It will have a vaccum hose coming off the booster and going to the intake manifold. The master cylinder with have hard lines coming off it which are brake lines. Hope this helps.
