My 85 honda accord is blowing white smoke out of the exhaust pipe in the rear and it appears to have something dripping onto the heat shield under the car, what do you think could be the problem?

check the brake system for any leaks. check the master cylinder for leaking out the rear of it. if you take the master cylinder nuts of that hold it to the power brake booster and slide the master off the booster and look at the rear of the master to check for a fluid leak or dampness. if you see this replace the master cylinder. also sometimes the power booster will suck the fluid were its drawn into the engine and burnt and the smoke will look white. another thing that causes white smoke is a bad head gasket as the coolant is sucked into the combustion chamber and burnt, it can also leak externally and cause the dripping you see.

1994 corolla...brake pedal goes to the floor after changing lines,brake booster and the there bleeder valves im missing?

Assumeing you have no big leaks in the new brake lines witch you would see because there would brake fluid all over the ground I would say you didn;t bench bleed the new master cylinder There is air in this part when you buy it and you need to get it out before it will work Heres how you do it first you need a kit it consests of plugs that you screw into the holes that the brake lines go into but they have fittings for hoses to plug on to them you put the master cylinder into a vice screw the plugs into the holes put the hoses on the fittings and put the other end of the little hoses into the cylinder resivior fill the resiviors with brake fluid then take some kind of a tool i like to use a 6 inch 3/8 ths socket extentoin because not sharp but you could use a screw driver And push the piotion in from the back of the unit repeataly until you see now more air bubbles coming out of the two little hoses that are in the resiviors like ten or so pushes Then reinstall hook up the lines and bleed at wheel cylinders with wheel cylinder bleeding always start at the fertist wheel and work your way back to the closetes wheel Its not as hard as it may sound good luck

Air in braking system?

Then master cylinder maybe damaged from the contamination,you may need to replace the master,try bleeding the master cylinder at the brake lines to clean it out,then start at the right rear wheel,then the left rear wheel,then the right front wheel,and then the left front wheel,do this in order.

Brake light on dash stays on but sometimes goes off when cornering. Whats wrong

Check your brake fluid level. If the level is low, it will cause this. Also- if the level is significantly low, have your brakes checked, or check them yourself. When brake pads or shoes wear down, the level of fluid in the reservoir will drop accordingly with it.

Constantly refilling brake fluid reservoir, can not find leak

this is not an uncommon problem.
if you are certain there are no fluid leaks anywhere in the system then look here.

the master cylinder is mounted to the power brake booster there are probably two or three nuts holding them together, remove these nuts and pull the master cylinder forward, now look in to the front of the power booster with a flash light, if you see any signs of brake fluid there than your master cylinder is bad. you want to correct this soon because that fluid is being sucked into the egine and through the combustion chambers. you should replace the power booster as well because it will be contaminated, although you can reuse the power booster untill it fails, i believe there is a gasket or o-ring in between the master cylinder and power booster aswell, make sure you look for it and dont leave it out.

good luck
