Sounds like your brake fluid is contaminated. You should have the system flushed.
Are the brake lines rusted out? If so I recommend replacing them all.
Yes 4 of them are rust out so I don't have to change the box connector that the lines are connected to under the hood the four lines because it has abs also and the light for the abs is on also so I wanted to know if I have to change that or just the lines because the lines are really rust out I could barely undo them to try to take it off but thanks so much
Unfortunately it sounds like you live in the rust belt and rust is a fact of life. I think what is happening....one starts to leak and you fix it, then when you use the brakes the next weakest one breaks thru the rust and starts leaking. Bottom line, yes you will need to change all the lines at some point or trade for a newer vehicle
OK if I change the break lines would it be good to change the master cylinder also and the ABS also or would it great i just do all six lines
Change the brake lines......and FLUSH out all the old fluid from the entire system. That will get you back to almost original......brake fluid absorbs moisture and I suspect the fluid has never been changed in 20+ years.....your lines could have been rusting on the inside as well as the outside. I would not worry about the master cylinder at this time if you do the above.
What is fluid absorb moisture is that something i have to buy
No problem....buy DOT 3 brake fluid........ the brake fluid absorbs moisture from the air over time, that moisture will rust metal parts it come in contact with.....that is why you flush out the old fluid and put in new, clean fluid
So should I buy some kind of solution to flush out the system when I redo the break lines
rubbing alcohol is cheap and can be used to clean system.
That's a good idea but how to I bleed the back breaks of it if I don't have a bleeder screw back there its drum breaks on the back of the car I bleed the front one I changed all four breaks today but still have alot of air in the system I have to press my breaks like 4 times for it to catch what do I have to do now
Drum brake wheel cylinder have bleeder screws that look just like the ones on the front disc brakes.
Ok i did bleed them but now the drive side don't want to bleed when I undo the bleeder screw no break fluid is coming out or the caliber its self its empty what could cause that because I change all the lines am bleed all the rest expect that one help me out here please thanks
You did not say if it is front or back drivers side......start where the new brake line ends, make certain fluid is coming out the line. If it is on the front you have a flex line from the hard line to the caliper,,,that could be plugged
Its the front driver side I just got a new line I will change that one an see if it works o
