The piston or cylinder can be warped and you will not be able to see it. if you have a precision hone you could hone out the cylinder and use fine emery cloth to clean the piston However if it's the front brake thats sticking only then I would think it has to do with the mechanical connections and not the caliper assembly. If it has a cable running from the hand brake to the brake cylinder check that the cable is not frayed. if it has a hydraulic cylinder undue the hose at the hand brake cylinder if the piston frees up then the cylinder has a bad check valve or junk in the fluid reservoir or hand control assembly. Let me know if you need more help with this.

I'm looking to buy a 2006 Piaggio Fly 150. I was told that the Valve adjustment service 6000 miles would be coming up and would cost about $200 - $300 does that sound about right.

Hi, Lori it all depends on your location a Piaggio Dealer in downtown San Francisco might charge $100 hr. labor plus parts and tax and various misc. shop fee's whereas a Dealer in Sleepyville Georgia might only charge $60 hr. I believe a 6K service is a major service that should flat rate around 2 hrs. so 2-3 hundred dollars is in the ballpark do your homework, check going prices at different shops if you have that luxury and take someone competent with you to look over the scooter and shed some light on whether it's a good deal or not. You can always use the cost of the pending service as a bargaining chip for price haggling. My email address is at the bottom get back to me with details and I can steer you in a safe financial direction, I was a Harley Tech for 35 years and my first scooter was a Vespa.

Right caliper is sticking on mitsubishi lancer 2002

The caliper is probably in good order. But rust is taking hold.Jack up the car,remove the wheel, and take off the two bolts holding onto the caliper. You can hang the caliper on the strut spring. DO NOT LET IT HANG BY THE BRAKE HOSE. Now remove the small brake pad sliders from the caliper mount and using a file remove all the rust that is underneath. In older cars when rust forms under the pad sliders it jams up the calipers making the brakes over heat. If you take off two more bolts you can clean the rust off the caliper mount at your work bench. Assembly is in reverse order and do not neglect to clean the rust off the caliper mount on the other wheel also.

Caliper goes back fine outer pad and disc goes blue ?

You will find that the caliper mount (that bit which bolts to the axle stub) is seized in the calip[er proper (that bit that has the piston). You will find 2 bolts that screw in from the anchor bit Undo these and pull the pins out. The piston housing will come out separate to the mount. Clean up the pin shafts and the holes they go into. Use never-seize in the holes and on the pins and re assemble. The caliper should now slide freely on the pins. Check all brakes and see that they all move freely

2009 Piaggio Fly 150 will not idle

It sounds like it has been stood unused for a very long period of time. It will be worth you taking it to a carburetor specialist and getting the entire carburetor stripped and professionally cleaned. Fuel, if left for a long time, goes bad leaving a coating that can block up various areas of the fuel system. If it's the fuel you got in the bike when you bought it, drain it and put fresh fuel in. (Dispose of the fuel safely and responsibly).

Just completed new back pads. Screwed in rear pistons with the tool and adjusted the parking brake. went for a test ride and rear passenger rim and rotor hot and smoking?

you may have to pull that side off and see if the caliper piston moves back in place freely,if not then you will have to replace that caliper and bleed the system.some times when you move the piston back when installing new brakes the piston seal rolls and causes the piston to stick/seize when the pedal is applied.

How can I change the rotors and brakes on a 2006 Cadillac?

Front brake
Step 1: Identify Front Disc Brake Components
Front Wheel Drive Brake Assembly
Most front disc brake components include: brake rotor, brake pads, brake caliper, caliper mount and brake flex hose. Brake service usual occurs between 20,000 and 40,000 miles depending on driver habits, road conditions and brake pad/ rotor materials used.
Step 2: Remove Brake Caliper to Replace Pads
Removing Brake Caliper Mounting Bolts
Locate primary caliper mounting bolts; apply wrench pressure counter-clockwise (When looking at the head of the bolt) to remove the bolts, upper and lower. Make sure the bolt threads are in good shape and replace if necessary.
Step 3: Remove Front Brake Caliper
Remove Front Brake Caliper
After removing the primary caliper mounting bolts lift the brake caliper off of the rotor and then tie or secure to the side, being careful not to bend or kink the brake caliper flex hose. Thoroughly inspect brake caliper and brake hoses for leakage, cracks or chaffing and replace as needed. Next remove the brake pads (If not mounted in the caliper) and secondary caliper mounting bolts. Notice how great protective gloves work, most technicians use them on the job today.
Step 4: Remove Brake Pads
Remove Front Brake Pads
Once the brake pads have been removed, make sure if there is anti rattle hardware to transfer to the new brake pads. Some brake pad manufacturers will include the proper lube (Caliper slides) and anti-rattle hardware to ensure proper performance of their product.
Step 5: Remove Caliper Mount
Remove Caliper Mount Bracket
Finish removing secondary caliper mount bolts and remove caliper mount. Note: clean and lube caliper slides and pad friction surfaces of all foreign material or build-up.
Step 6: Remove Brake Rotor
Remove Brake Rotor
With the caliper mount out of the way you can now remove the brake rotor. Sometimes it can get stuck so you may need to tap it with a hammer or use penetrating oil to free it up. Some manufacturers use small screws to hold the rotor on as well. Clean and inspect wheel studs, replace if any are damaged. Also clean bearing hub rotor mount surface to ensure the proper mounting of the new brake rotor. Inspect the ABS sensor wheel for cracks or damage and replace as needed.
Step 7: Depressing the Brake Caliper
Resetting Brake Caliper
To install the new brake pads you must retract the brake caliper piston. Remove the master cylinder lid or open the brake caliper bleeder screw to allow excess brake fluid to be released if necessary. Install C clamp tool and gently tighten clamp until caliper piston is fully depressed. Note: use old brake pad to protect the caliper piston. Close the bleeders once the piston is retracted completely
Step 8: Installing New Brake Rotor
Install Brake Rotor
Install new brake rotor, the new rotor is manufactured with a protective film over the rotor to keep it from rusting, remove protective film with brake cleaner before installing; also after the brake job is complete you may experience a small amount of smoke from the rotor when first used. This is normal and will go away after the first couple of uses.
Step 9: Installing New Front Brake Pads
Installing New Brake Pads
Reinstall the front brake caliper mount, and then install front brake pads. Make sure the pads are seated properly in the caliper mount; it must be a close fit to work properly..
Step 10: Reinstall Front Brake Caliper
Re-Install front Bake Caliper
Reinstall front brake caliper and reinstall caliper-mounting bolts, recheck all mounts and mounting bolts. Check the caliper slides to be sure there is no bind and that the caliper moves freely back and forth on the caliper slides. Bleed brake system per manufacturer's specifications to relieve any air trapped in the system. Before driving the vehicle, push the brake pedal down and let it up slowly, repeat until normal brake pedal operation resumes, this operation is forcing the brake pads to travel to the brake rotors.

Have a apachi 100cc quad which acording to the manufacturer has a yamaha jog 100cc automatic scooter runs fine for approx 30 / 45 mins then it looses power, it will still idle but every time u...

Losing power as the engine warms up is often caused by a sticking ring on the piston. This mostly happens on the exhaust side of the piston due to a lean mixture of air/fuel. Lean means too much air. what does your plug look like ? white+ashy? You may benefit by simply re-ringing the piston. It's easier than crank seals.
