I cannot see the leaking line in the video, however the brake line has a 10-inch connecting line from the caliper to the body. This line can be matched, and purchased.Soak both ends with PB Blaster before trying to take apart. You will need to bleed the four brake lines after switching out the defective line. Always start at the farthest wheel away from the master cylinder. Not a major problem. Hope this helps.

Brake lines probably broke. brakes stopped working suddenly.


There are many things other than brake lines that can cause braking loss. Investigation will reveal the issue. First, check fluid level in the Master Cylinder. If the level is normal, you don't have any broken lines/leaks. If the fluid is full and you have no brake pedal/braking power, chances are the Master Cylinder itself has failed. There are o-rings internal to the M/C that can fail, and when this happens, you will lose pressure to wheel cylinders/calipers and, as a result, lose your brakes.

If the fluid has leaked out, then you need to find out fro where. This is not too difficult normally. Fill the M/C with fluid and have someone press the brake pedal while observing the underside of the vehicle. You should see fluid dripping from somewhere, often near one of the wheels. You can have a leaking caliper/wheel cylinder, brake hose, or metal brake line. Once you determine what part has failed, you can purchase and replace the defective part. Brake calipers, wheel cylinders, and hoses are fairly simple to replace. Brake lines are more difficult, as they require shaping, cutting, and the creation of couplings. After repairs are done, the brake system must be refilled and all air bled from the system or braking will not be satisfactory.

Bakes aren't working after replacing cv axle


If you removed the brake caliper from the fluid line you will need to bleed the air out of the brake fluid lines.

I have brake fluid leaking near my right front tire. Any thoughts?


Yes, I have thoughts, stop driving the car immediately, as you risk loss of braking power... Usually leaks like you describe are either the brake hose or the brake caliper. Replace both sides on whatever you find.

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...

My brakes will not get hard. The pedal goes to the floor. I just changed rear caliper and rotor on the drivers side.


DId you bleed the system after you changed the caliper? If the Master cylinder lost it's fluid while you were changing the caliper, then there is air in the system and you need to bleed the entire system. start with the REAR RIGHT, then the REAR LEFT and then the FRONT RIGHT and last the FRONT LEFT. make sure the master cylinder NEVER runs low on fluid and DO NOT re-use any fluid that you get out of the calipers.

Rear wheel (left) brake fluid leak


First of all determine where the leak originates. At the outset make a mental note that the brake fluid will need bleeding at some point since if the fluid can leak out it is likely that air can bleed in. Air in the brake fluid is to be avoided as it impairs good brake function. First of all get the whole area clean. Use a small wire brush to remove all loose corrosion. Now check that there is plenty of brake fluid on the reservoir container above the brake under the hood, top it up as needed. 1) Bleed screw : Have a friend apply pressure on the brake pedal and undo (yes undo) the bleed screw just a quarter turn. Release about a quarter of a cup of fluid and then re-tighten the nipple before (this is important) the pressure is taken off the pedal. Clean everything with a cloth and tighten the bleed screw no ore than an extra quarter turn if this was the source of the leak. Check by standing on the brake pedal. 2) Caliper union : The flexible hose screws directly into the caliper and if it is leaking at the caliper just give it an extra tighten and then carry out (1) above. 3) Pipe Union : the other end of the flexible hose goes through a bracket and connects with the metal brake line. If tightening here, hold the metal junction of the flexible pipe steady and then tighten the brake line union nut. Do not be tempted to just tighten the nut on its own as the junction is liable to rotate within the bracket. 4) Brake pipe : Most brake pipes are made of steel (??!!) which as we know eventually corrodes. Most corrosion of brake pipes occurs either at unions or at brackets where water and salt can get to work. The only recourse is to change the brake pipe for a new length. 5) Caliper body : the seal between the piston and the caliper cylinder can sometimes be compromised by corrosion. You will need to remove the caliper/slave cylinder from the car to carry out a thorough inspection.

Brake fluid is leaking out the front left tire!


This is most likely a busted or separated line that is connected to the brake housing(on the front tire assembly). inspect the line for a tight fit. replace the line and coupler if found to be defective.

In most severe cases, the caliber may be faulty.

Changing 4 calipers and there is no oil com out when try to bleed


The master cylinder supplies the pressure to the brake fluid that travels between the maste brake cylinder resevoir and the brake caliper pistons (through the brake lines. If the master cylinder fails there will be insufficient compression of the brake fluid to make the calipers operate as designed. Leaks in the brake lines and/or cylinders is a possibility, and unrelated to functionality of the master cylinder. Also, pistons located in the brake calipers can form a corrosion ring on their inside walls if there is breakdown in the brake fluid or moisture that gets into the lines. Operating the vehicle when there is insufficient brake fluid in the master cylinder resevoir can also lead to air getting into the brake lines, causing bad working brakes. Air compresses more than brake fluid, and the master cylinder isn't designed to compress air in the brake lines. Sounds like a bad case of "lack of maintenance", as opposed to bad advice from the mechanics. That said, there's no excuse for bad installation. But, it's tough to improperly install a brake line since they are nothing more than hollow metal tubes. There should be no rubber connectors installed in the brake lines. When bleeding the brake lines one must remove all of the trapped air before you will see any fluid appear. If the valves in the master cylinder are not properly operating the master cylinder will not allow the brake fluid to get into the brake lines.

Hope this helps.
