There are many videos online that you can watch that go step by step on how to change drum brakes by yourself or you can even ask to watch the people at the shop to learn that way.
No, they are inferior to disc brakes. Drum brakes were used from the beginning of the auto up until the late 60s. Drum brakes are more prone to overheating than disc brakes. Disc brakes also shed water much better than drum brakes which improves stopping distance in wet conditions. Disc brakes apply pressure more evenly than drum brakes thus improving stopping distance. Disc brakes are superior in every way.
Watch how you take them off and put them back on the same way. Then you have to bleed them since there drum brakes
Specfics depend specifically on what type of drum brakes you have. The simplest way is to lift the axle, remove the wheels and the drums, and keep one side intact while you do the other side. That way, you'll always have a reference right there.
to take off a drum of your rear brakes you need a flat head screwdriver. simply place the screwdriver through the crack between the drum and the axel and pull in your direction all the way around and this should loosin the drum being able to get to your brakes
If its a rear wheel drive car it would be because more power to that axle, therefore more stopping power is exerted by the brake pads. When applying braking more forces are exerted on the front of the vehicle, this is why vehicles fitted with only one set of disc brakes (superior to drum) use them on the front of the car, and why front brakes usually wear faster. In your case I might suspect dragging brakes possibly caused by a sticking emergency brake cable. In most cases these cables are only connected to the rear brakes hence the accelerated wear. i would guess that either the emergency brakes are stuck on or the rear calipers should be inspected and or replaced. Or, it might just be, if you have front drum brakes, that the rear brakes are adjusted closer then the fronts were. If the front drum brakes were way out of adjustments (farther away from the drum) then the rears would contact first and then the fronts. You should always check/adjust drum brakes once or twice a year. I have not seen front drum brakes since the late sixties. The accepted course of action is normally every two changes of brake pads in the front a change of shoes in the back if complete inspection warrants this action. the only way brake shoes wear quickly in the rear is if the brake cylinders are jammed open then promoting the shoes to always be in contact with the drums or the emergency brake is sticking on when you release it. Have an inspection and correct your problem and save your money in the long run.
They take ceramic brakes all the way around and they change just like others.
The area in which you drum will not change the pitch but change the way in which you hear the drum. The sound may last longer or less, it may be loud or quiet.
Sounds like the rear caliper or brake piston is not releasing all the way. I would replace this and the rear brakes. It has possibly warped the drum or disk depending on if you have disk brakes or drum in the rear. Good luck.
diagram for rear drum brakes 1993 ford E 350 Most repair manuals have them . A trick my dad tought me was do one side before undoing other side . They are mirror image . That way you can look at it if you get stuck .
Sure could use some more information like the year, make, model and if this a front or rear wheel cylinder for drum brakes or a caliper for disc brakes.
Remove wheel if disc brakes: Remove caliper mounting bolts and slide caliper out of the way. If drum brakes: remove brake drum Remove brake line Hub assembly should be secured by 4 bolts You may have to separate backing plate from hub assembly, by supporting backing plate and striking hub assembly sharply w/hammer
If YOU dont learn how to introduce change into ur life then change will force its way in....and probably in a particularly devastating way
