When braking in reverse and turning while braking, there is a loud clunk in the rear end and a stutter in the brake pedal that feels like it is trying to push back against my foot. HELP

can bad wheel bearing/hub cause loud clunking noises?

rear brakes are sticking get it serviced

You can have worn bearings on the pinion gear and/or worn universal joints.

The rear suspension has no drive parts as your car is a FWD, front wheel drive. There are parts on the wheel axles which have bearings and also Brakes.
If you have rear disc brakes, the inner part of the rotor has a drum for Emergency brakes and these linings often peel off their brake shoe. The loose lining can get ground up in the turning rotor hub. The Emergency brakes are pinned to the brake backing plate and can clunk when the shoes shift. If you have rear drum brakes the shoes may be out of adjustment or worn out leaving room to rock as vehicle direction changes.
Bearings, excess play can cause noise. Suspension brackets, bushings within the mounts for these components can wear out. When parts are moving in 1 direction a "set" is grooved into the rubber parts. Changing direction of travel will unseat the part and make noise.
Traveling sound. You may be hearing a sound you suspect is in the rear of the car, but is actually a cradle mount around the Firewall. Sound travels through metal.
You need to get the rear wheels off the ground and check for play in all the components. For the cradle mounts, have someone ride the brake pedal and shift the transmission forward and backward to see if noise is generated or excess play is seen.

Sounds like a problem with rear brakes.If this vehical has drum style brakes if the brake shoe has become disconnected in some way it will usally wedge against drum in one direction or another.You need to inspect rear brakes.

Three things: Either the rear brakes are releasing, causing a clunk, try service and adjust rear brakes. If not, go to the drive shaft, check the u-joints and/or jack up the rear of the truck and rotate your tires by hand to see if there is a clunk in the rear end itself.

If fluid leaking from the master cylinder finds a way into the servo or booster it could cause an entirely different sort of trouble. Master cylinders are usually very reliable unless contamination of the fluid has taken place - usually indicated by a darker than usual fluid colour and sediment in the reservoir, evidenced when a strong light is used.

A loss of brake pressure could signal the master cylinder is failing (the pedal creeping towards the floor) or a brake booster problem, perhaps caused by insufficient vacuum or an air leak. An assistant is useful when looking for such problems and also when searching for noises.

The steady clunk being felt on the brake pedal might be something fairly obvious like a wheel balance weight just touching a caliper when the brake is applied. It is time to become a detective - I recently had one of those. One wheel had a second row of balance weights that caused no problems until I fitted new brake pads.

If a close and careful examination and a vigorous shake of everything by an assistant provides no clues, it could be worth checking the air gap between the ABS sensor(s) and the reluctors if they are the exposed type. Sometimes corrosion reduces the diameter of the reluctor and increases the air gap so the signal is lost at low speed. The ABS brain thinks the wheel is not turning and tries to operate the ABS on that wheel. Usually not a steady clunk but you never know, it could be worth checking...

it sounds like either your motor or transmission mounts are loose.also it could be the bearings in one of your transaxles.

Is the clunk noticed as soon as the brake pedal is released? Your brake shoes engage in the rear drum when the brake pedal is pressed and then release as the brake pedal is released. Your shoes may be worn and might be "hanging up" for a brief period, that would make a clunk sound your describing

have ya,ll checked the rear differetial fluid level.if u have an need more help feel free to email me at [email protected]
