Broken brake hydraulics can not be repaired
but ( and imagine this is correct)
If it has failed it is quite possible that it may be rebuilt.
In North America there is quite a few re builders that repair these.
There are many brake lines especially if the vehicle has ABS brakes. The brake lines would run from the master cylinder to the ABS module, from there one to each wheel for 4 wheel disc brakes or for rear drum brakes, one to each front wheel and one to both rear wheels.
Not usually. It is possible for the mater cylinder get suck in the apply position, but the brake pedal would not return to the up position after stopping. A more common problem for the brakes to be stuck applied is a locked wheel cylinder or brake caliper, or a jambed parking brake. These issues will be at one or more of the wheels, so check there if your brake pedal is at normal height.
I guess you're referring to the wheel cylinder brake backing plate at the wheel. The one which operates the rods that move the brake shoes. It's usually pretty obvious. A couple of bolts to remove and a brake line to remove from the cylinder. Bear in mind that you'll have to fill and bleed the brake lines after replacing the cylinder.
Brake lines and/or clutch line depending on vehicle. For brakes, the front brake lines usually attach to the frontmost connection, and the rear brake lines attach to the rearmost connection. Also of note, the front brakes typically connect to the largest of the two master cylinder reservoirs (normally the front one).
one common reason is that some brake fluid may have leaded out of one of the front wheel brake cylinders. Usually the car will jerk to the opposite direction of the leaking brake cylinder. Check the inside of the the wheel/tire and see if there are oil stains from the leak. if so you can replace the brake cylinder or sometimes change the dirt seals on the brake cylinder.
That is due to a lack of pressure in the brake system. More precisely, you are out of brake fluid and it has leaked , more than likely , from one of the brakes, or the master cylinder has failed. Do not attempt to drive it in this condition. You have NO stopping power. Call a mechanic immediately and have this fixed. Good Luck
It could be a bad cylinder, bad springs, bad emergency brake, or could need to be adjusted.
First you have to jack the car up after loosening your lug nuts and then you remove the wheel. After you do this, you have to pull the brake drum off. Next, dis assemble the brakes then disconnect the brake line from the wheel cylinder. Then you remove the two bolts holding the wheel cylinder on and put the new one in. Re install the bolts, and brake line, put the brakes back on, put the drum back on and bleed the brakes. Put your wheel back on and drive away.
Older cars had integral brakes, meaning that a proportional valve, which is the redundant part of a brake system that prevents total failure of brakes, if a brake line broke you will still have brakes on two wheels, and a master cylinder were all combined in one unit. A nonintegral brake unit typically uses a vacuum booster for power assist. The booster, the master cylinder, hydraulic modulator, and proportional valve are all separate units
Remove wheel and brake drum, disassemble brake parts, disconnect brake line from back side, remove 2 bolts holding cylinder on from backside of brake plate, install new one, tighten bolts, attach brake line, reassemble brake, reattach wheel, and bleed brakes.
Could be several reasons. Check the level of brake fluid in the reservoir. If one of the chambers is empty you have a leak, probably a rotted brake line, bad brake hose, caliper, master cylinder or wheel cylinder. Inspect all the brake lines from the master to each wheel, you will find a wet spot somewhere. Repair as necessary and bleed the system.
2 things to look for. See if you have brake fluid in the master cylinder. It has 2 sides one for the front brakes and one for the back. Look to see if they are full. If one is empty then look to see if you have a tire wet with fluid. If not then the master cylinder is shoot. R2 the cylinder and that should get you back in working order.
