AJK31 I would check your front pads and see how thick they are and also check rotors for high and low spots. Such has middle or something not being same height as the rest of the same rotor. Have them machined and replace pads if needed. I had a similar problem on my car I checked rotors and they weren't smooth as the rest in the middle had them machined at oreily for $20 and my problem went away.
As for rear moving up and down I have no idea what is wrong.

|05focusST91||Sounds like warped front rotors, check how much pad life is left in the front and if needed change your front pads/rotors, grease up the slide pins with dielectric grease and use brake clean on the caliper bracket to eliminate any brake dust.|

I have about 150 000 km or 93205.68 miles on my stock rear brakes and suspension. I had pretty bad front brakes before i replaced them around 120 000km.. The only thing i noticed was the peddle pulsated under braking, didn't move the steering wheel at all. I have a pooched Right Front strut and don't notice any bucking, I also feel as tho my rear struts are "tiring". Hopefully my information can possibly help you narrow down the problems with your car
*Also I do not have abs

If they are not adjusted properly it alone can cause the bucking you describe. With such low mileage you shouldn't need rear brakes yet unless you do lot's of stop and go traffic and live on a dirt road.

i see you drive a 2010 se. do you know if that was ordered with abs?
ive got 130k on my factory equipment and a recent inspection has showed ive only used half of the pads and the rotors have no scarring and thats with "spirited" driving and some track use. so your mileage should have nothing to do with it.
now as for the rear end bucking there could be a few things to look for. a bad absorber or a bad control arm bushing. the latter is hard to diagnose and to find out you need to remove it from the car. not a hard job- you should be able to do it in the driveway but remember that there is a great deal of spring pressure on it so you may want so coil compressors. you can get that at harbor freight for $16 or borrow it from autozone for nothing...
a shaking steering wheel could be from a warped rotor but that alone will not make your wheel shake as you have floating calipers. the rotors could be heavily warped and as long as the caliper can follow the profile you would never notice any performance loss.it is when the caliper binds up on its slides that you feel the shaking. grab a can of caliper grease and brake cleaner then disassemble the caliper. remove the slides and wash them with the cleaner and make sure to clean the wells where the pins ride in. then grease everything up and reassemble. there are also some stainless slides for the pads scrub those down and slap some grease on them too but make sure not to put too much on as the excess will get squeegeed of and most likely will end up on the rotor

|bile0026||Sounds like its time for new brakes and suspension :) Shaking wheel while braking is usually a sign that rotors need to be replaced. As far as the "bucking" it could be weak rear shocks. It's recommended to replace shocks/struts every ~60k miles (and maybe more often depending on the condition of the roads you drive). It's a bit hard to tell just from a description of the problem but that's what it sounds like.|

This sounds like a great time to visit your dealership so they can assist. I recommend making an appointment so they can perform an inspection and get this concern resolved for you. Let us know how things turn out.

|Gadabout||Just passing through; my quick guess; inspect your rotors and engine mount. (a combination of these two makes braking super scary, may just be time for rotors) . just an opinion to get the ball going =]|

My focus has 48,000 miles on the original suspension and brakes. I've noticed that when I am under heavy braking the back end seems to "buck" up and down. Also, when braking from about 60+ mph, the steering wheel shakes pretty violently.
Has anyone encountered this problem? Any idea what could be causing it?
