They do. Every time you back up and step on the brake, it activates the self adjuster. It has it's limitations. If you don't know how to manually adjust your drum brakes, have your mechanic do it for you. If you feel your brake pedal is mushy or you have to push it almost to the floor, it may mean your rear drums need adjusting.
Yes, of course you can adjust the rear drum brakes. They should be self adjusting. Every time you back up and apply the brakes they should adjust themselves. If that is not working, look for a small rubber plug on the back of the backing plate. Remove that plug and with a brake adjustment tool, you can adjust the brakes. Search Google for the proper procedure to adjust drum brakes.
The front brakes are disc brakes and are self adjusting. The rears are drum brakes and are also self adjusting providing the self adjusting mechanism is in working order.
If they are drum brakes then yes they are self adjusting, But they never adjust themselves right. You will need to adjust them. If they are discs brakes then there is no adjustment. ( replace pads)
Disc brakes are not subject to "fade" which occurs when drum brakes overheat and lose the ability to stop, another advantage of disc brakes is that they tend to stop in a straight line unlike drum brakes which often "pull" to one side. Yet another advantage of disc brakes is that they self adjust by drawing brake fluid in behind the piston while it is common for the self adjusters in drum brakes to seize due to corrosion then the drum brakes quit adjusting then the brake pedal goes lower and lower.
They are self adjusting. You don't have to adjust them. Problem is the wear limit on the drum is only 1mm. When worn to the limit the adjusters don't work.
there is self adjusting mechinsms in the drums. Just keep them lubed(ani-seize)
Disk brakes adjust themselves as they wear. Drum brakes have an automatic adjustment built into the brake system. When you back up and stop they automatically adjust themselves. If you remove the drum you will see the adjustment mechanism.
They are self adjusting but if you want to speed up the process, you can back the car up and pump the brake; each time you apply the brake in reverse it helps to adjust the rear brakes.
Only the rear brakes are drum brakes. The front brakes are disc brakes. To answer your question, twist the end wing nut by your drum brake. It tightens and adjusts how much you have to press on your rear brake lever.
Yes - Provided that the self adjusters have not seized from rust. That is quite common with drum brakes. Some year Sables have rear disc brakes. Those self adjust also. The Taurus /Sable rear disc adjusters are just as bad at seizing from rust as the drum adjusters. -On occasion I've even had to remove them and fit a whole new adjuster.
Its a bad cylinder spring
i'm not an expert on this..but i heard that brakes self adjust.
