How to install anti rattle spring 97 softial break pads

Sounds like the brake pads are rattling from improper installation or missing/broken brake pad anti rattle springs.

check that there are anti rattle springs behind the brake pads in the caliper on that side . When pads are replaced there is a spring plate that comes with the pads or there are little spring clips that are fitted with the pads to hold them securely in the caliper .. Compare one side with the other and see if there is anything missing on the problem side.

Tom, install the anti rattle spring on the rear caliper, Check the attached links,instruction and guides, Good luck

To your direct question - I don't know the Highlander model in detail, but as a general response, if the brakes are noisy when NOT applied, the piston in your new caliper may not be returning properly.

The return spring in disc brakes is actually the rubber fitted around the caliper piston. If this is causing the piston to be wrongly positioned, the brakes will be noisy. Check that the rotor can be turned by hand when the brakes are not applied. Also check that the piston is not retracting from the pads a very long way, which it should not do.

It is worth making very sure the spring clips are fitted correctly. Some can be easily put in the wrong way round.

If the brakes are squealing when applied, that is a different problem. You can get a disc brake anti squeal liquid, which is applied to the back of the pad on assembly to the caliper. Also double check all the anti squeal shims are correctly installed.

At this range, that's all I can think of right now.

1. Raise and support the vehicle safely using jackstands. Remove the wheel(s) on the side to be worked on.
   

NOTE: Removing a small amount of brake fluid from the master cylinder using a turkey baster

1. Drain a small amount of the brake fluid from the front reservoir using a suction gun or a turkey baster.
2. Place a C-clamp on the caliper so that the solid end contacts the back of the caliper and the screw end contacts the metal part of the outboard brake pad.
3. Tighten the clamp until the caliper moves far enough to force the piston to the bottom of the piston bore. This will back the brake pads off of the rotor surface to facilitate the removal and installation of the caliper assembly

1. Remove the C-clamp.
   

Do not push down on the brake pedal or the piston and brake pads will return to their original positions up against the rotor.

1. Remove the caliper mounting bolts. Tilt the top of the caliper outward and lift it off the rotor.
2. Hold the anti-rattle clip against the caliper anchor plate and remove the outboard brake pad.
3. Remove the inboard pad and the anti-rattle clip. Be sure that the support spring is removed with the inboard pad.

1. Use a piece of wire to support the caliper so that no tension is placed on the brake hose. Do not allow the caliper to hang by the brake hose.
   

To install:

1. Clean all the mounting holes and bushing grooves in the caliper ears. Clean the mounting bolts. Replace the bolts if they are corroded or if the threads are damaged. Wipe the inside of the caliper clean, including the exterior of the dust boot. Inspect the dust boot for cuts or cracks and for proper seating in the piston bore. If evidence of fluid leakage is noted, the caliper should be rebuilt.
   

Do not use abrasives on the bolts in order not to destroy their protective plating. You should not use compressed air to clean the inside of the caliper, as it may unseat the dust boot seal.

1. If not already in place, attach the support spring to the inboard brake pad.
2. Install the anti-rattle clip on the trailing end of the inboard pad's anchor plate. The split end of the clip must face away from the rotor.
3. Install the inboard pad in the caliper. The pad must lay flat against the piston.
4. Install the outboard pad in the caliper while holding the anti-rattle clip.
5. With the pads installed, position the caliper over the rotor.

Before securing the caliper, ensure the brake hose is not twisted, kinked or touching any chassis parts.

1. Lubricate the caliper pins and bushings with silicone grease. Line up the mounting holes in the caliper and the support bracket and insert the mounting bolts. Make sure that the bolts pass under the retaining ears on the inboard shoes. Push the bolts through until they engage the holes of the outboard pad and caliper ears. Thread the bolts into the support bracket and tighten them to 7-15 ft. lbs. (9-20 Nm).

CAUTION On models with manual/power brakes, pump the pedal until the caliper pistons and brake shoes are seated. On models with anti-lock brakes, turn the ignition ON and allow the booster pump to build pressure. Pump the brake pedal until the shoes are seated and the indicator lights turn off.

1. Fill the master cylinder with brake fluid and pump the brake pedal to seat the pads.
2. Install the wheel assembly and lower the vehicle. Check the level of the brake fluid in the master cylinder and fill as necessary.

Remember to rate this, good luck.

First off have you worked on brakes before, if you have not, carefully consider your options. Yhe caliper has to be removed, piston reset and new pads fitted. The most difficult part of the procedure, is R/R of the anti-rattle spring without breaking it.

Remove the road wheels, clean the exterior of the calipers. Remove the split pin from the retaining pins on either side and then remove the pad retaining pins and anti rattle springs. Remove the brake pads and clean exposed parts of pistons using new brake fluid. Wipe away excess with a lint free cloth. Using a piston clamp, press each piston back into its bore ensuring that the displaced brake fluid does not overflow from reservoir.
Refit the new brake pads, retaining pins and anti-rattle springs, using new split pins to secure them. Apply the service brake pedal several time to locate pads. Check fluid reservoir and top up if necessary using correct grade of fluid.

Front brake pad exchange guide.

Step1 Park the Dodge Durango on a flat surface. Put the emergency brake on and put wedges behind the wheels to prevent the vehicle from rolling. Disconnect the negative battery cable from the battery. Drain 2/3 of the brake fluid from the master cylinder, using a syringe. Remove the wheel and the tire assemblies. Step2 Compress the caliper piston back into the caliper bore using a large C-clamp to drive the piston into the bore. Use additional force if it is required. Using a 3/8 inch hex wrench or socket remove the caliper mounting bolts. Step3 Rotate the caliper rearward off the rotor and out from its mount. Remove the inboard and outboard brake pads. Remove the spring clip that holds the inboard brakes in the caliper. Tilt the pad out at the top to unseat the clip. Remove the retaining spring that secures it in the caliper. Unseat one spring end and rotate the pad out of the caliper. Step4 Suspend the caliper assembly from the Durango frame using mechanic's wire. Do not allow the caliper assembly to dangle from the brake hose as this may damage the brake hose. Step5 Clean the surfaces of the caliper and steering knuckle with a wire brush. Apply multi-mileage grease or similar product. Using brake fluid or break cleaner clean the caliper slide pins. Apply a light coating of silicone grease to the pins. Step6 Install the inboard brake pad and it's spring. Install the outboard brake pad. Install the caliper over the rotor and seat it in its original position until it is flush. Using a torque wrench, torque the slide caliper pins to 22 ft./lbs. Step7 Add brake fluid to the master cylinder. Bleed the brakes. Reconnect the negative battery cable to the battery. Start the engine and pump the brakes 3-4 times to seat the brake pads. Reinstall the wheels. Test drive the Durango at slow to moderate speeds to ensure that the maintenance was performed correctly.
Rear brake pad exchange.

Step1 Lift the Durango off the ground with a car jack. Support the vehicle on all sides with jack stands. Keep children and small animals out of the vicinity when you replace the brakes. Step2 Loosen the lug nuts on the wheels with a torque wrench. Remove the wheel and tire assemblies and set them aside, face up, to prevent damage. Step3 Compress the caliper and remove it by lifting the top up and off the caliper adapter. Hang the caliper from the Durango's frame with mechanical wire. Step4 Remove the inboard and outboard brake shoes from the caliper adapter. Take off the top and bottom anti-rattle springs. Keep the springs separated, as they aren't interchangeable. Step5 Press the piston into the bore with a C-clamp. To prevent damage to the pistons, insert an old brake shoe in between the C-clamp and caliper piston. Remove the C-clamp. Step6 Wipe down the caliper mounting adapter and anti-rattle springs with brake cleaner. Grease the anti-rattle springs with brake grease. Install the bottom anti-rattle springs, followed by the top anti-rattle springs. Step7 Install the inboard brake shoes followed by the outboard brake shoes. Replace the caliper and the wheel and tire assemblies. Lower the vehicle to the ground and pump the brakes to seat the pistons.
