Name of tool that takes off the rear caliper on a 04 expo?

Hey Stan the man,need your vehicles info.,year,make,model and engine size and Tommy on the spot here will send you a picture diagram of your rear brake assembly.There's a special spring tool you can get at auto parts store to remove and install springs,me got one.

you don't lube the piston only the studs that hold your caliper it have to slide freely on them some times rust, dirt or using the wrong tools for them cause them to drag or jam i hope thats your problem otherwise i recommend to have it checked by a specialist as you may have issues with the antilock valve body or the splitter !

Rebleeding can help. Always start on the longest line first. Passenger rear, Drivers rear, passenger front, then drivers front. You can also have a diagnostic machine hooked up to the ABS which will tell if there is a problem in sequential braking.

The ABS has its own valving and seals and sits in the middle of the flow to the brakes. The internal valving works on electric and that can be checked with a diagnostic plug. The Dealer will have one. It takes a better, more expensive scanner to do it aftermarket. Some Autozones, Oreillys, or Advance autoparts may have the more expensive scanner.

Sometimes it takes a power bleeder to overcome the ABS valving. I have had problems with Brake rotors on a 1999, 2002, and 2004 Ford products and usually in the front. I can give you several suggestions. Replace the front rubber lines. Under pressure fluid will flow to the caliper, but if the hose is getting smaller inside due to deterioration, it depends on gravity to return to the master cylinder. Your caliper will not fully retract and your brakes will overheat and warp.

Check out NAPA rotors compared to what you put on. I hope my solution is helpful to you.

Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.

Step 1 - Identify Rear Disc Brake Components
Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

There is special tool to release the pressure of a rear caliper piston.You must turn the piston clockwise and push on the same time

find out what tool you need to remove bolts for the caliper(2) once you get the bolts out remove caliper. next step remove old pads.then you will need a c clamp to compress piston on the caliper back in then get new pads and install them on caliper easy fix reinstall caliper on to rotor and put bolts back in just observe how the caliper came off

yes, you need a piston retract tool for the rear cylinders. rear piston must turn clockwise as it is being retracting.

'B6' (2001-2004) A4s dont have seperate rotors on the rear brakes like the pre 2001 A4s do. When changing the rear pads + discs the only special tool you will need is a caliper wind back tool. Let me know if you do also need to replace any ABS components aswell as I might be able to advise.

Continually push the brake pedal to set the brakes. (With park brake off). Brakes are self adjusting and will adjust to correct position.

just a toex head tool for the caliper pins
