19,100 miles and the front brake pads were down to metal on one side and paper thin on the other . Am I the only one who has encountered this ? Of course it's not a warranty item .

I'm guessing the driver side is worn more. It's due to the calipers being closer to master cylinder on driver side. If the pads wear too quickly it could be due to hanging calipers. Or weak rear brakes forcing front to do more work.

Rear brake replacement 2003 FLHT

The minimum brake disc thickness is stamped on the side of the disc. Maximum brake disc lateral runout or warpage is 0.008 inch (0.2 mm) when measured near the outside diameter.
Replace brake pads if the friction material above the backing plate on either pad is 0.04 inch (1.02 mm) thick or less.

To remove the rear brake pads begin by removing the right side saddlebag, loosen both pad pins but do not remove them or installation of the new pads will be more difficult than needs to be, remove the rear master cylinder reservoir so you can se the fluid level as you push the pads and the pistons back as the level ma rise too much when the pistons are seated fully in their bores and you may have to see this and remove excess fluid, pry the inside pad back pushing the pistons fully into their bores using a putty knife with a wide thin blade to avoid scoring or scratching the brake disc. THEN when the pistons have been fully retracted pull the pad pins part way out until the inside pad drops free and note the orientation of the pad so that you can easily install the new pad in the same orientation with the curved portion of pad necessarily facing the rear of the motorcycle, install the new pad and install but do not tighten the pad pins, then pump the rear brake pedal to move the inside pistons out until they
they contact the inside brake pad, then using a putty knife with a wide thin blade to avoid scoring or scratching the brake disc pry the outside pad back in order to push those pistons fully into their bores, verify that the inside pad is captured between the brake disc and the pistons, completely remove the pad pins to free the outside brake pad. note the orientation of the pad before it falls out and install a new outside brake pad using the same orientation with the curved portion of pad necessarily facing the rear of the motorcycle and if the inside pad moved during the previous step reinstall it. Replacing one pad at a time keeps the anti-rattle spring in place and so if you wish to replace the spring you will have to remove both pads to remove and replace it. THEN inspect the pad pins for unacceptable wear/grooving and replace if and as necessary and install the two pad pins and tighten them to 180-200 in-lbs (20.3- 22.6 Nm). THEN pump the brake pedal to extend the pistons and move the brake pads out against the brake disc. THEN check that the brake fluid is at the proper level about 1/8 inch down from the top of the reservoir and add NEW D.O.T. 5 SILICONE BRAKE FLUID, if necessary, install the master cylinder reservoir cover and tighten the cover screws to 6-8 inlbs(0.7-0.9 Nm), install the right side saddlebag, turn on the ignition/Light Key Switch and observe proper operation of the brake light, safely test ride the motorcycle and if the brakes feel soft or spongy, bleed them until you get a firm, hard pedal. Allow the new pads to properly wear in to the disc by not doing hard stops for the first 100 miles (160 km).

My double Cooler Master Cooling Fan R4-S4S-10AK-GP that i use underneath my laptop stopped working even though its not been in use for long time i bought it as part of a cooling pad with removable cooling...

If the fan spins and you find there is power going to it, then likely the electronic drive circuit has failed. You can get replacement fans at stores like Fry's and other sources.

A light in the dashboard turns on today and I have no idea what is the symbol for? is like a circle with 3 rectangles in line on each side this is a BMW 318i, 1996

This is the brake wear indicator. When the brake pads get too thin, this sensor, which is mounted in the brake pad backing on the front left wheel and the rear right wheel, touches the rotor and wears through, grounding out the contacts and illuminating the light.
Once the light is lit, you will need to buy a new sensor as well as new brake pads. The sensor is not expensive.
First step is to examine the brake pads and determine if you need front pads or rear pads or both. Don't be surprised if you need new rotors as well as pads. Check for a significant lip at the outer edge of the rotor. If the pads have worn in the sides of the rotor more than about 1/16", you are due for rotors.
You cannot go wrong with BMW branded pads. They are safe and work great, but they are really dirty. If you want to try other brands, read the reviews. Some squeak and some fade.
I use Mexican made Brembo rotors. They work well but they rust quickly, so the brakes squeak a bit the first time you press them after washing the car or driving in the rain. More expensive rotors or BMW branded rotors don't rust so much, but they cost a lot more and don't necessarily last any longer.
After replacing the pads, turn the key to the On position and leave it on for about 90 seconds before starting the car to reset the brake pad warning light.

When you hear the front passenger brakes screech does it mean they need replacing

The brake pads do. There's a thin piece of metal on the pad that will drag on the rotor when they get then to let you know that they are thin and need to be replaced. If you don't replace them soon, you could wear all the way down to the metal backing plates, and ruin your rotors, which will be quite a bit more expensive.

Front brakes are sticking on and off on 2005 vibe,when the brakes stick brake pedal becomes hard??both sides start to heat up,calipers seizing?master cylinder problem?or?????

Ok Have you recently replaced the pads? Do they act normal after they cool down? Are the pads in good condition, pads that are so worn that the caliper pistons come out beond their normal limit may stick there due to excessively worn pads. If so make sure they are at least factory grade quality Good are bendix, the only thing that can cause your symptoms is a bad master cylinder because it affects BOTH front calipers equally if it was a caliper it is likely to affect only ONE. Let me ask you this happens after driving in heavy traffic or after along drive?
If So there have been countless cases of boiling brake fluid, Old Brake Fluid gathers moisture and its boiling point is lowered, Fluch out ALL the old brake fluid and have new put it.

also is there any chance even the slightest chance that something other than brake fluid even a drop or two is enough to do damage. has been added to the master cylinder at any time? If so you need to replace EVERY PART IN THE BRAKE SYSTEM INCLUDING THE ABS CONTROLLER THAT HAS ANY RUBBER PIECES IN IT CALIPERS HOSES WHEEL CYLINDERS,MASTER CYLINDER just for your information.
I believe you have a bad master cylinder but do not buy a rebuilt one only bran new and preferably from the dealer.
Please contact me if you need more help and would you give me a good rating if you feel my information is helpful.
Thank you ,Randy

Battery cover for Olympus camedia C720

Go to homedepot and get a small (1.5" x 2" x 1.5") L-shaped THIN METAL BRACKET used for bracing shelves. One side of the L is longer -- slip this between the bottom of the camera and the tripod pad that holds the camera, with the shorter side of the L parallel to the side of the camera. Push the short side of the L tight against the camera body and tighten the tripod screw, securing the longer section of the metal brace under the battery hatch.

It's not quite a fixed hatch, but it works great for me. The key will be whether your tripod has a mounting pad big enough to secure the L-brace enough to keep the battery cover closed under pressure. I have a Mohawk tripod with a detachable mounting pad and it's perfect.
