Breaks not working and break fluid drains very fast

Breaks stopped working. I put in more break fluid. They worked for a little over a week then the fluid was empty again. Now within only a 10 mile round trip the fluid is empty and breaks are gone. I think it is the slave cylinder on the passenger side. How can I tell before having to take it all apart?

Yes you have a leak in a line or a wheel cylinder or your proportional valve or caliper it might help to tell us what kind of vehicle you are driving but if it's a line get the same size line and 2compression unions and a tubing cutter if other components then replace good luck Stephen

No its a brake line .You need to look for what is leaking and ware .The best way is to cut out the bad spot with a tubing cutter get a short peace of line the same diameter you will have to get a flaring tool but don't worry about double flaring the new tube the new connector will seal but you will have 2 flairs

SOURCE: Break Fluid Leaking, empties every three days

You should be able to look around each tire and see where it is coming from, let me know if any of them have brake fluid on them, if so it is a brake cylinder leaking, if the leak is somewhere else than I may can help you with that, oh and when you do find the problem I can probably save you some money on the repairs.

SOURCE: the break tube from the right tire has rotted off

The front brake tube rotting off would cause you to have no pressure and letting the pedal hit the floor. The smoke from your rear tire is an indication that the rear brakes are not working properly, only one wheel is braking and it is overheating.
You can replace the front line yourself, but it has to have the air bled out after the new line is put on. Chances are pretty good that you need a whole lot more than just one line though. You'll be smart to replace both front lines.There is a good chance that the bleeder screws on the front calipers will break when you try to bleed them so be careful.
You would be wise to take it to a shop and have it checked over before you start to find out exactly what all you need to replace before you start.
This truck is DANGEROUS to be driving and should be fixed right away. If you are involved in an accident, your brakes will automaticly put you at fault and you could have some hefty bills because of that,so be careful. Hope this helps.

SOURCE: auto transmission slips then grabs

first thing i would try is changing the transmission fluid out and filter, i beleive its almost 8 quarts. use a full quart of lucas transmission additive with the new fluid. if this doesn't help, the transmission will either need replaced or rebuilt

SOURCE: break goes down lower then normal but the breaks

I it is usually the brake shoe adjusters at the rear.

Auto adjust type:
To adjust them you can hold your foot hard down on the brake pedal and wrech up the park brake lever a few times

Manual adjust
Drums off and wind the adjuster cog to increase the diametre of the shoes, don't get carried away thow or the drum wont go back on

SOURCE: I have a 96 ford

Check your parking brake. if it goes down to the floor or does not hold, then your back brakes needs adjusted. bad master cylinders bleed off slowly to the floor while pushing on the brake pedal. If you need assistance on adjusting let me know.

I need a 1968 oldsmobile torando manual. i have recently finished paying off my beautiful 1968 oldsmobile torando. and she is having some break issues when reversing.please help

I do not have a shop service manual ... but you may have braking challenges in general if this 1968 still has drums up front. This car was notorious for not having good braking (if all 4 wheels had drum brakes).
Anyway ... was the brake fluid real low? ... below the minimum add fluid line? If it was still in the safe zone before you added any more fluid ... then you could have several issues:
  • contaminated brake fluid
  • hole in brake line
  • master cylinder issues
If the fluid was below the minimum .... then there is probably a leak somewhere ... and should be inspected
Does the parking brake still work? That may help you troubleshoot.

Ok about a month ago my rear passenger brake locked up when it was wet. It slid a little but I got stopped. It only did it that one time. And about 3 weeks ago I drove it to the store that night and it...

They're probably right probably is the master cylinder but now you have Air the lines so you will have to fill up resivor then pump the brakes up and crack the line then you will need to keep the brake pedal depressed till you close the line it takes 2 people repeat process over and over till fluid comes at you must remember to fill the main reservar as you do this if you get all the air and still have brake problems it means that it probably is the master cylinder but it doesn't hurt to change the brake fluid at anyway

I have a 99 voyager and today when I went to stop fast to avoid a deer I stopped but then my brake! Light came on which I think is abs light and my breaks are barely breaking....my fad says could be break...

ABS sensor(s) could be bad or dirty/misadjusted. If the sensor stops working, it thinks the wheels are locked up and will modulate the brake pressure causing the braking distance to be scary long. Have it looked at ASAP. The sensors are at each wheel and point right at the toothed wheels on each axle. Check fluid first of course.

Break failiure

Well sounds to me like you might have some moisture in the fluid which can cause the breaks to fail. Have your break system flushed totally out and refilled. Brake fluid is very touchy. If you leave brand new brake fluid bottle open for a few days it will draw moisture from the air and ruin the fluid.
