Try rebleeding the brakes for the possibility of a wheel cylinder becoming airbound. Also check brake pad hold down pins, as possibly one or both have come loose. If it is a rear wheel drive car, you may have a drive shaft universal joint that is going bad. Your self adjusters, if you have them on your rear brakes, should be checked too, as it prevents one side to make pad contact and the other not to.
@vwbobby I agree with your point about friction, hence anything big and heavy uses drums! The problem with drums is the need for regular adjustment and inspection. A build up of dirt or grit can destroy shoes in a few days. Drums tend to stay damp.
Under heavy braking conditions they can overheat causing a pocket of air to form under the shoe that expands and renders them useless. Uneven friction can also cause weaving and disastrous results.
Disc self adjust, self clean and easy maintenance.
Well since I have changed my brakes every now and then I hear a thud from the back of my car kinda like I have something rolling around in my trunk but I don't.. could it be my drum brakes.. changed shoes and drum in back and rotor and pads in front so everything is new.. it's been 5 months since I changed them
Thanks

Naturally the bleeder needs to be at the top.

@vwbobby Disc brakes - easier manufacturing, better heat dissipation,
less complicated, easier servicing, not effected by water,
no build-up of dust and as somone else commented - why don't
race cars use drums? - get real!

@northeasteg6 Isn't that just so logical? Because that's where the air will be
during bleeding

@XavierHolland there are still cars manufactured with drums.

@leaper1950 the bleeder needs to be at the very top of the caliper

@MrAxesyko28 only if you can do it, and you intend to drive the car in the way that you will need rear disk brakes
