There are two reasons i know of . first the oring in the piston is either cut or twisted. The other is that the o ring on the piston is to small. The only cure is to replace it either way.
Seal in brake caliper is leaking and needs replacement Flexible brake line to the caliper is leaking and needs replacement
just replace the whole caliper.
Brass washers replaced when caliper replaced?Fitting tightened completely?
Rebuild the cylinders on that caliper.
If the caliper is sticking or leaking it is possible to buy a rebuild kit and replace all parts that are worn inside. If the caliper has a cracked or broken housing then the unit can not be repaired and must be replaced.
If it is leaking, cracked, or the piston is seized it needs replaced.
how do you get the brake caliper push in to put new brake on
That depends on where it's leaking out; if it's at the master cylinder, you have a bad master cylinder, if it's at the wheel cylinder you have a bad wheel cylinder if it's at a caliper... well, you get the idea. If you know how to repair a master cylinder, wheel cylinder or caliper, you can often get by with a little savings but it's usually best to just trot down to your local auto parts retailer and get a new or rebuilt one.
what is the best way to bleed brakes when installing new caliper on front left wheel
NO, and in fact what you are proposing is extremely dangerous !The only fix for this is a new part fitted by a competent professional.
Jack up the 2002 Optima and remove the wheel. disconnect the caliper brake line and drain into a bucket. Unbolt the caliper, and remove it with the pads. Bolt the new caliper on and replace the pads. The brakes may be spongy and the new caliper will require bleeding.
remove the caliper slider bolts and the brake hose then put the new caliper on, dont forget to bleed the new caliper and top off brake fluid when finished
Probably brake fluid, your caliper seal may have gone bad
There is NO adjustment screw ANY where on the caliper. When putting new pads in, the caliper piston must be pushed in so it fits over the new pads.
A leaking shower valve by installing a new cartridge.
Could be the caliper or the metal line. You will have to have it checked.
Failed caliper, wheel cylinder, hose, line, Vehicle is unsafe to drive.
To replace a faulty brake caliper with a new caliper or a rebuilt caliper and assuming that is all it needs, a garage would probably charge you one hour of labor plus the cost of the caliper and brake fluid. Call your local auto parts store to get a quote on the brake caliper.
Remove the caliper retaining bolts from the inside of the caliper. Lift the caliper off the mounting bracket and over the rotor. Slide the old inner and outer brake pads out of the caliper, and slide the new brake pads into the caliper.
Expanding the calipers (when you put in new brake pads) can cause the master cylinder reservoir to overflow. Before attempting to perform repairs, make certain it isn't simply leaking out of the master cylinder reservoir. HOWEVER... If it's leaking at the left front wheel, you'll probably need to replace the caliper. Sometimes a hydraulic cylinder, such as the caliper cylinder, can become pitted and when the rubber seal of the piston crosses the pitted surface it can leak brake fluid. Simple answer, find out where it's leaking, it may be nothing, it may be something to repair.
Remove caliper mounting bolts Slide caliper off rotor Use a "C" clamp to fully retract piston into caliper body If parking brake is used on this caliper piston is threaded and a special tool (not expensive) is required to thread piston into caliper body
First unbolt the slide bolts and pull the caliper from the rotor. Take the pads out. Then support the caliper with wire or bungee cord or whatever. Now also support the new caliper near the old one. Undo the bolt that the line goes to and remove it . Now bolt the bolt to the new caliper. MAKE SURE to use new brass washers usually supplied with the new caliper. Remove the old caliper out of the way. Put the new pads in and replace the caliper onto the rotor. Then bleed the caliper. There is a bleed screw on the caliper. Connect a plastic see-through tube to this bleed screw then have someone pump the brakes and hold them. Open this screw to push the air out. Keep doing this until you see nothing but fluid in the tube. Its easier if you use a closed ended wrench with tube running through it to do this. Now it should be done. Good luck.
Use a screwdriver to lever piston back (between caliper and front of piston). remove caliper, usually two bolts, remove pads from caliper, fit new ones same way. re-fit caliper.
Remove 2 caliper bolts, squeeze piston back,remove old and fit new pads. Wirebrush slider then re-fit caliper.
