You need to BClear. But I'll try to answer anyway. A line could be damaged trying to repair somthing else, raising on a lift or trying to repair it or another one. Brake lines are funny, especially in the northeast where we have cold and ice and salt. Fuel and brake lines rot out. If this happens to you, don't screw around, replace them all before you go through multiple repairs and heartache. When they get weak from rot, simple movements cause them to fail. If you try to fix one, another begins to leak as they are generally run together. Pukenstein@aol.com
If there is no fluid coming from the brake line, there are two possibilities: 1. there is no damage in the brake line, merely air in the brake line. 2. The brake fluid may already be completely depleted. To find out, get some water with a bunch of dish soap in it, but try not to make a lot of suds. Pour the water over the whole brake line and watch the line while someone pumps the brake pedal. If bubbles form, then there's the hole. No bubbles? Air in the line or perhaps damage in the master or slave cylinder.
replace brake line the damage to the line or if the jb weld gets into the line it will affect how the system works.
To effectively loosen a brake caliper, you can use a wrench to loosen the bolts that secure it in place. Make sure to support the caliper to prevent damage to the brake line. Once the bolts are loosened, gently wiggle the caliper to remove it from the rotor. Be cautious not to damage the brake line or other components.
It is important to replace a brake line at the first sign of leaking. A brake line is a fairly simple repair, first you must remove the old line using two wrenches on the hex bolts. Then you screw the new brake line in place using the wrenches and replace fluid.
Remove the line and replace it. Then make sure to keep the master cylinder full while you & a helper bleed the front brake caliber. Be sure and use brake line tools and not open-end wrenches or you will damage the brake lines.
If it is a front brake problem it could be a frozen (stuck) caliper, collapsed brake hose or a pinched brake line. If it is in the rear it could be a frozen e-brake cable, pinched brake line or a frozen wheel cylinder.
You could have a leaking wheel brake cylinder. It could also be a bad brake line or a bad master cylinder.
To unclip a brake line on a 2004 Chevy Impala, first ensure the vehicle is safely elevated and secured. Locate the brake line clip, which may be held in place by a retaining clip or bracket. Use a pair of pliers or a flathead screwdriver to carefully release the clip, being cautious not to damage the line. Once the clip is removed, you can disconnect the brake line fittings using a brake line wrench to prevent rounding the nuts.
Could be a restricted/damaged brake hose or brake line on the left front.
someone sits in the car slowly pressing the brake peddle while you have the brake line open. When finished bleeding the brakes, don't forget to refill the master cylinder.
Any sudden brake loss can be the cause of 1. brake line damage 2. master cylinder disfunction
First you disconnect the brake line and place it into a large bowl. While someone is adding fresh brake fluid, press firmly on the brake pedal until all air is gone from the line.
