So today I was driving and the brake line busted. I manage to get home using the e-brake. My mom and I went to AutoZone and got a new one and my dad put it on, and some more brake fluid in it, but the front brakes still don't work. Nothings leaking anymore. The fluid just isn't getting to where it needs to go. Any ideas???

 

Did you bleed the brakes?

 

I don't believe my dad did. I assume all the brake fluid had ran out anyway. Why?

 

You have to bleed all the air out of the lines and the calipers for the brakes to work properly. Theres bleeder screws on the tops of the calipers to bleed the air out.

You always have to do this if you open up the braking system in any way.

 

If the master cylinder ran dry, you'll have to take it off the car and 'bench bleed' it first...then do all 4 wheels.
A search will help you find out haow to bench bleed.

 

you can bleed the master in the car no need to remove it......where you get that carzy info... just crack the lines like a bleeder and fluid will come out with any air. why go doing extra work.

bench bleeding is easy to do when changing a master but by no mean the only way to do it.

 

If you let the master cylinder run completely dry you will need to bleed your entire system. No need to remove the master cylinder. I have all the steps listed below and these are the steps directly out of a Haynes Manual.

To bleed the master cylinder bore -
1. Remove the vacuum reserve from the brake power booster by applying the brake several times with the engine off
2. Be sure to check brake fluid levels periodically through the bleeding process (don't want more air in your lines)
3. Disconnect the forward brake line from the master cylinder bore until brake fluid begins to flow out, then reconnect the line.
4. Have an assistant depress the brake pedal very slowly (one time only) and hold it down.
5. Loosen the forward brake line at the master cylinder to purge the air from the bore, retighten the connection, then have the brake pedal slowly released.
6. Wait 15 seconds (Important)
7. Repeat the sequence, including the 15 second wait, until all air is removed from the bore.
8. After the forward port has been completely purged of air, bleed the rear port in the same manner.
9. Next you will need to bleed each individual wheel in this order. (Important) Back Right, Back Left, Front Right, Front Left. If you also need instructions on how to bleed each wheel refer to this thread, https://www.thirdgen.org/techbb2/sho...hreadid=264045

If you follow this procedure as listed I guarantee you won't have any more air in your lines. I actually did this last weekend, so I know it works well.
