If this is a metal line tube nut on a flare fitting, then make sure you are using a line wrench. If rusted try PB blaster or another good penetrating oil. As a last choice it may require heating the caliper slightly where the line screws in with a small torch or induction heater. Use caution not to burn yourself or catch the car on fire. Most penetrating oils are flammable. Once the line brakes loose gradually work it back and forth until it loosens up.

If it uses a bolt with copper sealing washers then you can use the same procedure. Leave the caliper mounted and use a 6 point socket and ratchet to brake the bolt loose. If this does not work try an impact gun and the appropriate 6 point impact socket. Just remember to be patient.

In the event that these methods fail or if you overheat things with the torch and damage the hose then you can probably replace the brake hose for $20 to $30 but don't forget you gotta get the fitting on the other end of the hose loose without damaging it also. Good luck.

remove the tire and make sure the outside of the brakes are free of corrosion. try loosening the brake caliber bolts, wiggling the brake pads, and recompress the brakes.

How do you remove the front disc brakes?


To remove the front disc brakes , you must remove the break caliber assembly . Keep in mind that on some brake calipers a special Torx Drive T40 or T45 must be used to remove the caliber bolts from the spindle assembly . Also , Allen (Hex) bolts are sometimes used . Be sure you have the right tools .
1. Properly block both rear wheels at the front in the back of each wheel.
2. Loosen the lug nuts on both front wheels one turn on each nut.
3.Jack up and support the front of the car on Jack stands with the wheels one to 2in. off the ground.
4. Remove the two bolts on the inside of the caliber the secure it to the spindle .
5.Once the bolts have been removed the caliber should pull straight away from the rotor and spindle assembly .
6.Remove your old brake pads , clean the assembly , properly lubricate the moving parts as necessary , especially the floating sleeve as the assembly is called a floating caliber which means half of the Caliper is bolted to the spindle (inner) but the other half floats (outer).
7.Use a large see clamp centered between the caliper piston and caliper housing to push the piston all the way back into the caliber cylinder by turing (1 turn at a time) the screw until the piston is flush with the caliber face .
8. Install your new brake pads .
9. use the reverse procedure to assemble everything back together. Good luck and be safe....

Rear break caliber


If your having a leakage from this, or if your rear brakes are locking up, replace both calipers (one on each side) and replace rear brakes if necessary - (if replaced, it's best to replace front as well, but not necessary if they are still good).

Please let me know if you need further assistance.

After changing pads and roto's on the front the brake petal goes to the floor and won't recover pressure? I didn't loosen brake lines or bleeders


You obviously got air in your lines while you were changing the pads. The brakes now need bleeding. Once you bleed them, your pedal will come firm again. But the good news is that you will only have to bleed the front brakes....Please don't forget to rate this answer for me...

Rear drum brake caliber


You don't have calipers in drum brakes. you have wheel cylinders that activate the brakes when pedal is pressed. The brake cylinder is located at the top of the brake backing plate on the rear wheel. the brake line is screwed to it on the outside and two small bolt hold it in place. remove your brake springs, shoes etc., then remove the brake line and bolts. Before removing the brake line and bolts spray them with WD40 or something similar to loosen the rust around the fittings.

2004 Chevrolet Silverado Extended Cab brake replacement


jack the truck up and take the passangers tire off. look behind the rotor you should see 2 bolts holding the caliber on to the rotor. loosen those and take them out. from there you should be able pull up on the caliber this will take the caliber and pads off together. take the pads out of the caliber and install the new ones .

BECAREFUL not to twist or bend the caliber to much or you will bend the brake line.....

once you have installed the new brake pads in the caliber. put the caliber back on the rotor. if they will not fit release the bleader valve to release the pressure. than you should be able to slid the caliber back onto the rotor. once you have done that close the bleader valve. reinstall the 2 bolts to hold the caliber in place. put your tie back one. Follow these steps for the other side.

now once that is done. you might want to blead the front breaks.
what you do is have someone help you. fill the brake resiviour with brake fliud. than start your truck.
Have someone in the cab to press the brake. What you want to do is turn the wheel so you can get to the bleader valve. once you can get to it open it up. have the person in the cab other truck press the brake until you see a steady flow of brake fluid coming out of the caliber. once you see that have the pseron press the brake once more and hold it to the floor.
close the bleader valve.

now do the same thing on the other side. But, make sure you check your resivour fluid first.
This is to make sure you don't have any air in the lines. after you are done with both side put it in gear and hit the brake make sure you stop......... If that works go about half the block down and hit the brake again to make sure you stop......
once you have done that and are comfortable with the way the truck stops than ou are good to go and now know how to change the brakes for future refrence..... be aware the back brakes are diffrent.........

let me know when you are ready for the back brakes.
do not blead the front ones if ou intend to do the back brakes afterwarwords......

if you are only doing the front brakes you must blead the the passanger side first......... if you do not have the bolts holding your caliber on than you will have a pin the you will take a hammer to and knock it out that will release them....
