they dont need that good of brakes to stop
My 98 rodeo has disk brakes in the rear not drums,are there drums on some models.
All modern mass-produced cars and light trucks DO have hydraulic brakes on the front and the rear wheels. Heavy trucks generally have air brakes on all the wheels. Maybe you are thinking of cars that have disk brakes on the front and drum brakes on the rear? On cars, these are both hydraulically operated using the same hydraulic (brake) fluid. In normal stopping situations, the front brakes do more work than the rear brakes. Maybe 70 or 80% of the braking is done by the front wheels (it depends on where the weight is in the car and how fast you stop). Disk brakes are a somewhat better brake for a car, but drum brakes are a little cheaper to manufacture. So, disk brakes are almost always used on the front wheels where the braking is more important. Drum brakes are used on the back of some cars to save money. Note that performance cars (sports cars) almost always have disk brakes on all of the wheels.
Disk brakes? they push in or twist in clock wise This applies to all disk brakes. If the piston is a hollow cup, it pushes in. If the surface is flat with a line across it or a hourglass or some other figure on the surface, it screws in.
If the car is older, it might only have rear wheel anti-lock brakes(RWAL) a lot of pickups pre-2000. some times tire tread can cause that if the tires have different traction abilities, or different brake pads on the from and rear.. also could be proportioning valve issue.. does it have rear drum or disk?
No, most of the stopping is performed by the front brakes. But Honda uses a braking system that applies the rear brakes first. For this reason the rear brakes on some Hondas will wear out first.
What year? Most are rear disc from some where around 79 and on?
They are self adjusting. Some sdjust when backing up and hitting the brakes and some by using the parking brake. You can also adjust them by removing the rear drums.
Some models of Ford Ranger have ( 9 inch ) rear drum brakes
every cavalier (unless modified) has rear drum brakes and front disk brakes. Wether it has ABS or not doens't effect the changing of the brakes, it needs front pads and rotors, and back needs drums and shoes... so the front is different from the back You should disconnect the battery cable as a safety procedure so the ABS will not try to work when you are working with the brakes. Just be aware that in some GM you will need a password to unlock the radio, so be cautious about it. Good luck.
the brakes were not fixed properly some part is installed wrong
No, they use foot operated rear brakes, as on all bikes. Some riders, Mick Doohan for instance tried a rear brake that was operated by a button on the left handlebar....
Some recommended rear bike racks that are compatible with disc brakes include the Topeak Explorer Rack, Blackburn Outpost Rear World Touring Rack, and Axiom Streamliner Road DLX Rack.
