Rear brake noise after brake replacement

Did you replace ALL the pads on BOTH sides? They are usually sold as sets of 4 so use all 4. Did the pistons in the callipers push back smoothly? Sometimes a 'sticky' piston can cause a pad to rub causing noise.
Is the sound constant or does it pulse under light braking? Pulsing can possibly be a warped rotor 'tapping' the pads as the the warp passes them. The warp can be tiny and you'll need a specialist tool, (A Dial Gauge Indicator), to measure for it.
Deeper tone noises can suggest it is the rotor causing the issue.
Commonly rotors can last between 30,000 to 70,000 miles depending on how hard they are used. Did you check the condition of the rotors when you changed the pads. On a 2015 model there is a chance these are the factory installed discs. So it could be worth you changing them anyway.

if you replaced all the brake parts I would check your hub bearings and cv axels if the noise is coming from front if the noise is in the rear check your e brake shoes located inside of the rear brake rotors if u have disc rear brakes or your rear brake bearings .. hope this helps

hi any kind of screeching noise normally means uve got a metal on metal contact so i wd say u probally need ur pads changing also the rust that forms is totally normal when not used for a while goodluck

You did not mention working on the rear brakes, so I must assume that the rear brakes are still original equipment. Perhaps the grinding noise is coming from the rear.

Installing new brake pads on toyota camry solara 2006 front rotors and pads and rear pads. Steering wheel would shake while breaking on 50+ miles per hour speeds. All fixed now.

Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

The rear brakes should last from 30000 to 60000 miles or 50000 to 100000 kms. So something is wearing out your brakes too fast. Are you doing the work or some shop. I also assume you have discs and not drums since you mention pads and calipers. I am not certain but usually you need a tool to turn the pistion in when putting in new pads. I would make sure the pads are releasing properly by raising rear of car, stepping on brakes a few times (with engine off and try see if wheels are free by spinning by hand, also try to use handbrake a few times and release it and see if wheels spin freely. Maybe rears always applied. Notice burning smell, are discs glazed from heat? Are you using really cheap pads. Also check the proportioning valve which will decrease pressure to rear brakes during hard braking. Do you notice rear wheels squeling during hard braking. Do you have antilock brake system? Also are you using good quality pads and rotors.

i have a 2003 toyota 4-runner my brake and abs vsc are on and it has a beeping loud noise.....what do u think is the problem?
