You will need to bleed the brakes. The easiest way to do this is to have a second person if you don't have a power bleeder.
You should have the vehicle on a level surface, then starting at the farthest wheel from the master cylinder (right rear) have your helper pump the brakes several times until the pedal is firm. Then have your helper keep constant pressure on the brake pedal while you loosen the bleeder (a small nut with a hole in it located towards the top of the brake backing plate on the rear). If this vehicle has 4 wheel disc brakes the bleeder will be located at the top or highest portion of the caliper. You should check that you have a full master cylinder of Dot 3 brake fluid and make sure the cap is on securely after you have bled each wheel. Running the master cylinder out of fluid will only cause you to have more bleeding.Only crack the bleeder open far enough till you see, feel or hear air come out but make sure to tighten it before you helper reports the pedal is on the floor.
You will need to be quick. Repeat this on this wheel till you get a solid stream of brake fluid coming out. Then move to the left rear and repeat.
Once done on the rear you will need to remove the tires from the front to have access to the bleeders on the caliper.Again starting on the left front repeat the procedure then move to the right front.
By the time you are finished your pedal should be firm and towards the top. If its not you may need to replace the brake pads and shoes and have the rotors turn or replaced. If you have rear drum brakes you should make sure these are properly adjusted up also. This too can cause a spongy pedal.

I changed rear rotors and pads, now when I push the brake it goes to the floor then builds pressure as I push it. What could be causing this?


If the brake pedal was ok prior to changing the brakes that shouldnt be the problem unless you have disconnected or opened a brake line. If the rear calipers are the wind in type and the park brake is part of the caliper, most likely the pistons are not lined up correctly with the caliper housing

I have a 94 chevy corsica. When I push the brakes itg goes all the way to the floor. It stops but it takes a while I checked the brake fluid Iits full.


Sounds like you have air in your brake lines, which you need to bleed the air out. Have a friend pump your brakes while you go behind each wheel and open the line just a tad. When the fluid comes out close the line off. Have your friend pump the brakes again and hold the pedal down while you allow the air out. Keep doing this until the line is solid with just fluid coming out. Start with the wheel which is the furthest then the next furthest, etc
Have the correct brake fluid on hand, I would get this done ASAP. I had got into an accident didn't know I had air in my lines till I ran into a off duty cop in his Very at a stoplight. Good Luck!

What the brake bleeding sequence for my 95 prizm? How do I know if the brake lines need to be repaired?


all basics....
longest to shortest order. just look at lines you can see where they go in 5min.
rusted or leaking or crushed lines are bad. super basics.
damaged, no , only the bleed valves were touched and yes they do break, and for sure in salt belt. (wiki that)
its needs bleeding,
if the MC and slaves (all parts) dont leak there is air in the system.
if all air is out (i use pressure bleeding) but if all out, then the MC is bad.
spongy is always air , bleed again, repeat.
get a book on brakes, see how to do bleeding 6 ways.
some ways are better, or like me I use 3 ways.
keep in mind , air wants to float up, and tell me which way are you using... 2man way? opposite of the float rule?
sure. its classic way and can be very hard.

Brake pedal soft when truck is running, gets hard like standard brakes when pedal is pumped


Sounds like your brake system has air in the lines. You will need to bleed your brakes starting with the longest line from your master cylinder. be sure your master cylinder is full and open the bleeder valve on the furthest line and have someone slowly push on the brake pedal till it is to the floor then close the bleeder and have the pedal returned to the rest position. Continue until no air comes from the bleeder. Move on to the next longest line and repeat until all lines are clear of air. Be sure to not run master cylinder low of fluid or you will have to start over. Let me know if this helps. Thanks.

Brake paddle goes to the floor before it has brakes


Im guessing you have air in the lines, possibly from a leak in a caliper.. You need to inspect the brake lines and calipers to determine a leak. Most brake shops will do this for free...

No brakes I think the booster was going out because my peddle got soft but would still stop me then i changed my brake pads shortly after the brakes completly went out and can now only stop with the...


The problem is not the booster, the job of the booster is to make braking easier. If the booster went out the brakes would be hard to press.
Your soft pedal is likely due to air in the brake lines. Bleed the brakes and go from there.

Brakes- Light on, pedal to the floor to stop. Whats wrong?


It is likely that you have air or water in your brake lines. If you know that your break pads are good, I'd suggest you bleed the brake lines to remove old fluid, any air pockets and any water that has condensed in the lines causing the soft pedal effect

I have a 1996 Ford Mustang that has no brakes what so ever. THe brake pads are good and we blead the brakes to no luck. Dont know what is wrong with it please help.


Your master cylinder must be loosing pressure or have a faulty seal. Also if you have any air in your brake lines you will need to start over because the brakes will not work with any air in the lines. Check your brake lines for holes or leaks.
