How to replace ear cushion on bose QC 3 headphone


The ear cushions are held on the earcup with six snap fasteners, three on each side. To remove the ear cushion, simply pull it away from the earcup carefully so that you do not break the plastic snap tabs.

It should not be necessary to pry the ear cushion off with a sharp object, but if you do, be careful. There is also a thin gasket seal between the earcup and the ear cushion, take care not to damage it.

If you need to replace the ear cushions with new ones, they are available from Bose for $35/pair.

EAR CUSHION


Sony parts suppliers sell replacement ear pads. Part no 2-320-280-01 about US$16 each (not pair).
Old ear pads slip off - pull gently to stretch the part that sits in the groove of the headphones until one side slides out.

The creative sewer can remanufacture new pads from thin soft leather by following the pattern of the old ones.
No cost fix is to scrape off the remaining peeling urethane leaving the soft fabric backing. Headphones will still work but the soft earpads should absorb high frequencies.

How to replace ear pads?


If you use a headset frequently, it's important to change the ear cushion periodically. Ear cushions absorb a lot of sweat, dirt and makeup and can breed bacteria if not cleaned or replaced as necessary. This can lead to bacterial ear infections in extreme cases. Repeated and frequent use can also cause foam ear cushion to deteriorate and break into pieces over time.

Need earpad replacements for Optimus Pro-100 Wireless headphones


Just flip the headphone pad inside out on the Optimus Pro 100 wireless headphones.
Find the 3 screws on each headphone speaker, you have to push the existing cover back, but you'll find them. Remove the 3 screws. Be careful of the speaker wire that will be attached to the cover plate that has the ear pad on it. Also, look carefully at how the components are assembled inside the headphone, as you might disturb their setting. They are easy to return to their proper place if they move.
Gently remove the ear pad, turn it inside out and you will have a new covered ear pad. GENTLY, re-install ear pad onto speaker plate, be careful not to break the speaker wire that is attached. I found a little flat screwdriver helps to pull the edge of the pad over the plate. The ear pad is actually quite strong and can take some abuse, but don't pull the speaker wires loose.
After you have the cover back on, find the screw holes and put the 3 screws back in. Presto, a little cleanup on any loose pieces of covering from the original side and your done for another couple years or so.

Need to replace 1991 chevy astro van break pads and rotors and need a diagram


The following procedure requires the use of a C-clamp and slip-joint lock pliers.
  1. Siphon off about 2/3 of the brake fluid from the master cylinder reservoirs.

CAUTION The insertion of thicker replacement pads will push the piston back into its bore and will cause a full master cylinder reservoir to overflow, possibly causing paint damage. In addition to siphoning off fluid, it would be wise to keep the reservoir cover on during pad replacement.

  1. Raise and support the front of the vehicle on jackstands. Remove the wheels.
When replacing the pads on just one wheel, uneven braking will result; always replace the pads on both wheels.
  1. Install a C-clamp on the caliper so that the frame side of the clamp rests against the back of the caliper and so the screw end rests against the metal part (shoe) of the outboard pad.
  2. Tighten the clamp until the caliper moves enough to bottom the piston in its bore. Remove the clamp.
  3. Remove the 2 Allen head caliper mounting bolts enough to allow the caliper to be pulled off the disc.
  4. Remove the inboard pad and loosen the outboard pad. Place the caliper where it will not strain the brake hose; it would be best to wire it out of the way.
  5. Remove the pad support spring clip from the piston.
  6. Remove the 2 bolt ear sleeves and the 4 rubber bushings from the ears.
  7. Riveted style brake pads should be replaced when they are worn to within 1/32 in. (0.8mm) of the rivet heads; bonded style pads should be replaced when they are worn to no less than 1/32 in. (0.8mm) of the backing plate.
  8. Check the inside of the caliper for leakage and the condition of the piston dust boot.
To install:
  1. Lubricate the 2 new sleeves and 4 bushings with a silicone spray.
  2. Install the bushings in each caliper ear. Install the 2 sleeves in the 2 inboard ears.
  3. Install the pad support spring clip and the old pad into the center of the piston. You will then push this pad down to get the piston flat against the caliper. This part of the job is a hassle and requires an assistant. While the assistant holds the caliper and loosens the bleeder valve to relieve the pressure, obtain a medium pry bar and try to force the old pad inward, making the piston flush with the caliper surface. When it is flush, close the bleeder valve so that no air gets into the system.
Make sure that the wear sensor is facing toward the rear of the caliper.
  1. Place the outboard pad in the caliper with its top ears over the caliper ears and the bottom tab engaged in the caliper cutout.
  2. After both pads are installed, lift the caliper and place the bottom edge of the outboard pad on the outer edge of the disc to make sure that there is no clearance between the tab on the bottom of the shoes and the caliper abutment.
  3. Place the caliper over the disc, lining up the hole in the caliper ears with the hole in the mounting bracket. Make sure that the brake hose is not kinked.
  4. Start the caliper-to-mounting bracket bolts through the sleeves in the inboard caliper ears and through the mounting bracket, making sure that the ends of the bolts pass under the retaining ears of the inboard shoe.
  5. Push the mounting bolts through to engage the holes in the outboard shoes and the outboard caliper ears and then threading them into the mounting bracket.
  6. Torque the mounting bolts to 37 ft. lbs. (50 Nm). Pump the brake pedal to seat the linings against the rotors.
  7. Using a pair of slip-joint locking pliers, place them on the notch on the caliper housing, bend the caliper upper ears until no clearance exists between the shoe and the caliper housing.
  8. Install the wheels, lower the vehicle and refill the master cylinder reservoirs with brake fluid. Pump the brake pedal to make sure that it is firm. If it is not, bleed the brakes.
