brake help .....

i just changed my front brake pads. Everything was done how its suppose to be but now i have a problem. when i test drove the trucks and apply breaks the truck dosent stop . The break pedal is pressed in completely and still no drip from front breaks whatever it is, its from the rear ... What did i do wrong ? how do i fix this ?

 

its sounds like a bad brake hose or maybe you have it twisted

 

it was just fine before the pad change, i dint even touch the brake lines or bent anything ... how do i bleed the brakes ?

 

you had to remove the caliper to replace the pads
it is poss that you have the hose twisted

 

i changed the rotors too so i took the whole caliper out and replaced the roter ... what do you mean by its twisted ? about how many times should i pump the break padal for it to become normal i sis about 25 times yes my brake resevoir is full

 

ok just so i understand what you are saying
are the brakes going to the floor
if pump them do you get brakes

 

yes the brake pedal is going all the way to the floor and the brakes are not applying .... truck does not stop

 

If you also did the rear drums, and didn't properly set the star adjuster, you might have this symptom. When you apply the brake pedal all of the fluid in the brake system will go the path of least resistance, if your rear shoes aren't making contact with the drum the fluid will go back there, and you will never get front brakes to engage.

Turn the car off, and apply the parking break, if you feel no/little resistance then this is your problem. To fix, you can either remove your rear drums and re-adjust, or you can pump the parking brake again and again, you will hear the rear brakes make a ratcheting noise, do this as many times as it takes till your parking break feels "right" again.

 

If you didn't remove your brake lines, you shouldn't HAVE to bleed the system. Since you spread your pistons apart however to get the new pads in there, it will take a few pumps to get the pads seated back on the rotor. You stated however that you have pumped the pedal 25 times or so, and that should be more than plenty. If you still have no pedal pressure:

1. Check the system for a leak. The front brake lines on my '05 aren't rubber but metal, so when I do any brake work I don't move the caliper any further than necessary and hang them via a piece of twine from the coil springs. Is it possible you moved the caliper too far and kinked/split one of the metal lines?

2. Did you remove the brake line from the caliper at anytime?

3. Did you remove/loosen the bleeder screw at any time without pressure being applied to the pedal?

4. Did you disassemble the caliper in anyway or lose one of the pistons and simply push it back in place?

5. Did you fool with the rear brakes at all?

6. What do you mean there is no drip from the front brakes, only the rear? Do you have the bleeders open or something? If trying to bleed be sure to constantly check your master cylinder to ensure there is brake fluid present. If you run the MC dry you will have to start all over.

 

if only did the front start at right front have someone inside the truck
pump the pedal tell you get one then have him hold the pedal down
open the bleeder on the caliper do this tell you have all the air out
then do the same on the left front
if you did all the brakes start at the r/r then l/r then l/f r/f
and ck the master for brake fluid

 

did not touch the rear drum at all

 

1 & 2. i did unscrew the metal breaklines but dint bend or move them at all ... there is no crack or leak on them . i unscrewed them both again and break oil is flowing through it properly as it should.

3. Only removed the rubber cap but did not loosen the bleed valve ( golden color with a hole on it ) at all

4. Calipers are fine the way they are suppose to i have changed brakes on many cars before never came across a situation like this ....

5. Dint touch the rear brakes at all

 

ok does the truck needs to be on idle ?

 

if you are working br your self open the bleeder so brake fluid can flow
keep an eye on the master so run out of fluid when you get a even flow
close the bleeder and do the same on the l/f

 

no

 

You removed your brake lines and introduced air into the system, now you have to bleed. You probably didn't run into this on past vehicles because you didn't remove the lines. No matter the make/model, remove lines = bleed.

Might as well head to the parts store and pick up some fluid and a "one man bleeder" or equivalent. It allows you to bleed the brakes by yourself, but isn't necessary. I bought one this spring for around $10 and have used it several times on the Taco and motorbikes - love it.
