ive got a 92 chevy caviler, it blew a brake line and i fixed that?

Question

now i cant get the brakes to pump up so i can bleed the air off, the pedal goes right down to the floor,?????any ideas would help alot

yeah i did all that Dusie but it feels like it just wont build up pressure , when i step on the brake i can also hear it pushing air around the vacuum booster and master cylinder

Answer 1

several things may have occurred, so i will assume the worst
1. the brake line that blew , was it a steel line?did you replace it with a new steel line with proper connectors and double flared tube ends?
2. if it was the flex hose at one of the wheels, did the replacement hose match the old hose exactly? are the other flex hoses in good shape ? do they swell up in diameter when you push the brake pedal? they should not.
3. are there any other leaks in the system? [rear wheel cyl's are famous for leaking at high mileage on these cars]
4. if all of the above is in good shape and you used proper materials and procedures, then suspect failed master cylinder [on older cars even with low mileage brake mud collects at the end of the master cylinder bore and the simple act of pushing the pedal to the floor ruins the rubber cup seals on the piston . at this point you must have a new or rebuilt master cylinder.
be careful jacking and blocking as you can be dead onely once.
wear eye protection when bleeding and clean any spilled brake fluid from bodywork before it eats the paint. and good luck

Answer 2

Since you blew a brake line , this incident should be a sign that the rest of your brake system should be looked over by a certified mechanic. I'm all for doing it yourself but when it comes to brakes. It takes only one time to realize just how important this is. To answer what else it could be. My guess is you need to bleed your lines. When ever you change a device that causes you to lose a severe amount of fluid. It warrants you to Completely bleed your brakes and check all of your wheels for leakes. If you blew one line I would have the others inspected for swells. Hope this helps and please be careful.

Answer 3

check to make sure the master cylinder has brake fluid in it. it may help if the car is running or not. try to bleed both ways car on and off. you may have another leak or problem. you should not pump you brakes at anytime to bleed them it causes air to mix with the brake fluid, with bleeder tight hold break down loosen bleeder let air out tighten bleeder and release pedal and repeat. but keep master cylinder full you will loose more fluid this way but have better brakes in the long run. hope i helped.

Answer 4

have someone pump the brakes for touyou and keep bleeding the brakes at each wheel. after a while the brakes will start pumping up. some vehicles for some reason takes a while.
