Autozone carries speed bleeders for the rear discs of all cars.
I have a set from them - Like $8 IIRC - made bleeding the rears cake. I bled the front with a vacuum pump.
Some cars have different front bleeders (like mine) and they do not carry that size. The others uses the same size as the rears.
Oh yeah. Don't forget to bleed the clutch (if applicable) while you are at it. It shares it's fluid with the M/C and likes fresh fluid too.
