My daughter has her rear brake pads and rotors replaced 2 months ago and 3,000 miles ago at a well know tire/brake store. In the past few weeks the vehicle started making noise from the rear. She took it to a local shop who said:

BRAKES INSPECTED REAR BRAKES THAT WERE RECENTLY REPLACED FOUND REAR PADS WERE FLIPPED AND THE INSIDE PAD WAS PLACED ON THE OUTSIDE THIS CAUSES THE CALIPER TO NOT SEAT PROPERLY FOUND WRONG SLIDE GREASE WAS APPLIED TO SLIDE PINS CAUSING SLIDE PINS TO BE SEIZED THIS MADE THE LEFT REAR CALIPER STICK WEARING OUT THE PADS ON ONE SIDE TO METAL ON METAL REPLACE PADS, ROTORS AND CALIPERS NEEDED

She took the vehicle back to the original store and was told that the pads are all the same and it doesn't matter which way the are put on. Also that the grease is irrelevant.

Wondering if anyone had any input on this.

The pads can be flipped inside to outside; except the wear indicators should be on the inner pad. The grease is very important; it has to be very high temperature caliper grease. Otherwise regular grease will bake under high temperature and will solidify and cause the pins to seize. Find a good shop to deal with.

Thank you for your response. Are you saying the pads can be installed incorrectly?

It is possible to install brake pads incorrectly on some vehicles while on others they are completely interchangable. Some vehicles have specific inner and outer brake pads and also left and right can be different. Pads can have raised "nubs" on the backing plate and if switched, may contact the piston or outboard caliper "fingers" if placed in the wrong position, causing the pad to not be parallel to the rotor. Also, some pads (typically inner) have metal "wear sensor" tabs and "typically" the sensor should be positioned so that it will contact the rotor first when the rotor is going forward (top or bottom depends on calipers being mounted in front or of the rotor hub). However, some vehicles may be set up differently. When DIY, always pay attention to how the pads come out! Some mechanics just pull the pads and slap in new ones without ever checkingo_O

As a follow-up to my last post - Brake pads from my 2013 Altima, rear and front. Outboard rear are interchangable (L&R) but not inner to outer-notice pins on inner pads. Notice that "wear indicators" are on both inner and outer front pads and opposite ends of each set. Switching will position indicators at either top or bottom of caliper. Why do inner and outter have different shims, no clue:rolleyes:

Looking at the FSM, it shows an extra shim cover on the inside pads. The shim design approach was engineered in an effort to eliminate pad squeal when braking. I've been using AKEBONO premium pads for years which have one shim glued on each pad, inner and outer. No squealing. Enough said!
