Allen wrenches usually come in a set, try 3/8.

I have done brake work for 50 years & never had one problem

So whomever is doing your work isn't doing what is necessary

If all rust is removed from all mating surfaces,& all sliding surfaces
& anti-seize is applied to those areas, you won't have any problems

Silicone Brake Lube to the caliper pins

You have to machine the rotors properly & you have to use quality
pads-Raybestos or Wagner & their best,most expensive ones

Once a year min you start over & repeat the rust removal & lube
You only need to machine or replace rotors every 2 to 4 years

Brake Fluid-- HAS TO (MUST BE) Replaced/Flushed every 2 years

Parking Brake Cables can not be rusted inside & hung up

I'm 100% sure they never removed any rust,never lubed a thing,
& there is rust on the wheel bearing hubs,rotor faces,back of wheels
& even used an air gun to over tighten the wheels

That is what the butchers at all shops do

When a vehicle is built, it comes off the assy line bone dry
& the brakes rust on a the rail cars for 5 weeks getting to a dealer

More than likely a brake pad,or pads holding on rotor.This can be a bad caliper or bad caliper brake hose.

You open the bleeder valve
Then you need a tool, to turn in the parking brake ratchet,clockwise
As your turning in the piston,it will also push back into the caliper

After you have pads on,ratchet up P-Brake by hand

Then bleed all 4 wheels
RR
You do not bleed ABS,but you do however have motor running
and a helper to slowly press brake pedal, as you open and close
bleeder approx 10 times,until clear fluid and no air.

Do this every 2 years (bleed)

You will not find an LS tool. Buy the $9.00 square combo cheapy
and file a little off one of the two pin sides, to fit

When you turn the piston, be sure the notch is up,I think,so the pad pin goes over it

Use Raybestos Ceramic Pads on front and back
Backs were Ceramic OEM and fronts work well and no dust.

Sand off all rust everywhere,anti-seize on all caliper mounting stainless
slippers and pad ends.
Both sides of rotors,back of wheels etc.
May have to file off paint from pad ends, to get a nice fit and sliding free

Hello, to replace the rear brake pads follow the following steps:

1. Lift the Chevy Impala with the jack and place it on jack stands.
2. Remove the wheels with a lug-nut wrench and set them aside. The lug-nut wrench can be found in the trunk of your Chevy Impala.
3. Remove the caliper with a ratchet and use a bungee cord to hang the caliper. Do not let the caliper hang from the brake hose, as the hose might break and cause fluid to leak.

4. Remove the brake caliper bracket from the steering knuckle with a ratchet. Set it aside.

5. Remove the break rotor from the hub. The rotor might require force to be removed; if it does, use a hammer to hit the rotor in the center, where the lug studs are located. Take care not to hit the studs.

6. Remove the new rotor from its packaging and use brake cleaner to remove the grease from the rotor. Grease is applied on the rotor in the factory to inhibit rust during storage.

7. Install the new rotor onto the hub.

8. Install the caliper bracket with new brake pads onto the rotor and fasten it to the steering knuckle. Use a ratchet to tighten the bolts.
9. Open the master cylinder reservoir so you don't break a seal while compressing the brake caliper.

10. Compress the brake caliper with a C-clamp, so that the caliper can fit over the new brake pads. Install the caliper by securing it to the brake caliper bracket with a ratchet.

Thanks

Try your parts store for this one. They have a wide range of different brake pads for your vehicle with prices going up for the better ones.

I use Wagner on my 1997 Cadillac deville that do not require shims as they are built in.

These are fool proof pads.

Good luck to you...

There is no set mileage, many factors come into play. Weight of car, driving habits, where you are driving (highway/city) all determine how long they will last.
However, one rule generally applies: You will go through two sets of front brake pads for every one set of rear pads. This is because the majority of a cars braking happens in the front. Most pads have wear indicators, softer metal that makes contact, and sound, when the pads are getting low. Keep your ear out for this strange grinding sound. It's time to replace the pads! Hope this helps.

The best way to answer you question is to tell you to take the vehicle to your nearest dealer and inquire with the parts dept. I can tell you that on the ffront of your car you have rotors and the brake used on the front is called a pad. Also your vehicle does not have a separate parking brake. It is the same as the regular rear brake no matter which type of brakes you have on the back.

Best choice without serious study and experimentation are OEM replacement parts from dealer (likely more expensive than "discount" parts, but they work!)
