so the other day i was noticed my rear antilock brake light and the other brake light came on. and when i was driving when i would let off the gas it would slow down faster than normal. but now it doesnt slow down as fast when i let off the gas. and when i push on the brake pedal it has almost no pressure behind it till im bout an inch from the floor board. pllllzzzz help, idk what the problem is.

o and another thing is that i have to fill up the master cylinder resevoir bout every three days cuz the brake fluid gets low pretty quickly

 

Start looking for where there's fresh fluid - start at the master cylinder and trace each line to the respective wheel. Best guess right now, you have a bad brake cylinder or caliper and it's leaking. With losing that much fluid on a regular basis, it should be fairly easy to find the thing.

 

well i had a buddy of mine look underneath while i pumped the brakes and he said brake fluid was squirting out of the break line that goes to the rear driverside tire. so i went to oreillys to find the price on break line and he said he needed to kno wat size brake line i needed.

what size brake line would a 1991 f150 use and do i need special tools to bend the brake line?

 

You can get a brake line kit for about $60 and install it yourself. Or pay labor at the dealer and see what they can do. Either way, the F150 brake line parts are compatible from the 80's to about ten years ago. There were no real brake throughs (get it?) in brake line tech and lots of Fords are standard for parts to cut down on costs to the consumer. Just be safe on the road!

 

thx gravedigger, that was helpful. thx to everybody else too. my gf's dad is gonna help me fix my brakes today and hes a diesel mechanic and lots of his buddies have him fix their stuff so hes gonna help me fix my brakes.

 

I would suggest you go to the "vendor's showcase thread" TASCA is a Ford dealership that sells OEM part for cost plus 10%. I ordered a clock spring from them and it was cheaper then the local Ford dealer and they have a fast turn around. They properly use the vehicle identification number to get you the correct part. Get your VIN number and ask Josh for a quote.

 

Very cool! No problem. good brakes are the most important and they aren't the most expensive part of the car to fix. Good luck, and please let us know how it turns out! Oh and if you can snag some DIY tips from your girlfriends dads friends, feel free to share -I'd personally like to learn some more tricks of the trade! Be well!

 

well i found out it was a rusty brake line that had cracked. so we replaced the rusty brake line and it was done. we also recharge my A/C. total cost : $33. not bad for good brakes and cold A/C. sad part is i didnt learn any neat tricks but im sure i will.

 

Awesome, that's always great when you can fix what you need at a steal. Once me an a buddy of mine scratched up a test car off roading and were freaking out because the manufacturer was picking it up the next day. So we filled up the tank and were deciding what to do when this guy who was admiring it turned out to be a body guy. He literally fixed everything on the spot for $40 bucks.

 

nice, i wanna paint my truck but with body work and materials its gonna be like 4000
