Rear Rear brake caliper & rotor removal/installation

Rear brakes on the galant are fixed discs and pads/ with handbrake operation through the main caliper.

bleed the rear brakes & also u can goto auto zone & get a tube of brake lube that goes on brakes to stop squeeling!

you get a voltmeter and check the ohms reading from the brake sensor see if it still works correct or broken hope this helps

For sure in front and mostly drum in rear.

The Galant has both front and rear stabilizer bars. Be sure to check and make sure one of the ball joints have not popped out. You can see the rear stabilizers by looking under the rear bumper at the inside of the wheels. This could be the source of the problem or possibly the bushings that hold the bars are shifting and banging when you apply the brakes.

do you have the emergency brake set perhaps? You'll need to tap them with a hammer and a pice of wood as well.

SOUND LIKE WHEEL SENSOR.CHECK THE REAR TIRE THAT HAD A FLAT TIRE.CHECK TO SEE IF WHEEL SENSOR WIRE IS IN CONTACT.OR DAMAGE WHEEL SENSOR.IF ALL IS GOOD.LET DEALERSHIP SCAN IT.TO CHECK THE ABS BRAKES SYSTEM.

it could be the spark plugs, at least that is what it was for mine, if you have over 50k miles without a spark plug change i highly suggest one, also a oil /transmission change would be great for your car too if you haven't done those reciently. I would also suggest using a higher grade gas, sometimes this fixes the trick too.
If you try all those and still experiencing hard transitions please let me know and i'll try a more indepth analysis on your car.
Thanks jyotsna.

remove your rear wheel then remove the brake assembly. there are 4 bolts that hold the hub to the rear axel with anti lock brakes you will have a wire to remove from the hub. it may tak a large hammer and chisel to remove the hub. but it will come off. then reinstall (if there is any shims behind the hub they must be put back in in the same directions (these are alignment shims) some have some dont. tighten bolts and test drive the ca 5 miles or so. then retighten the lug bolts. and then again after 100 miles.
hope this helps
