New front brake pads installed on wrong sides ( upside down )

[odie]

Those rotors look rusty and very rough surfaced!!

They're new rotors . Checked them and tire pressure about a mile down the road in a parking lot . Also , there's been plenty of moisture along with road salt ( w/ and w/o dirt ) since the replacement .

But does the tab placement matter? I’ve never heard of it mattering. I think your theory has too much you-tube.

Is it squeaking or grinding? Squeaking is common especially if it’s a pad-only change. I often have to at least rough up both sides of the rotor with a belt sander and then do a good bed-in. Some pads are harder to manage this than others. Grinding/crunching means something is wrong. Or maybe the pad is running against an area of the rotor which the previous pads did not. Solution? Keep driving it until it wears in, or replace the rotors.

If you take it back, be prepared they may tell you it needs new rotors. They would rather replace the rotors than take it apart 3 times to eventually fix a squeak. And sometimes, even new pads and rotors don’t set right, but if this is an active shop they should have parts they have goo experience with.

I'm going with the manufacturer placement of the pads with the wear indicator tabs on top since placement from the factory . The designers very likely have a reason .

Forgot to mention that a few days after the install of the new RAYBESTOS R-Line ceramic pads and POWERSTOP coated rotors there was a good amount of vibration ( not steering wheel ) when backing up to the left . It only happened that one time . Reason being pad(s) moving or other ? Possibly because pads were installed on wrong sides with the wear indicator tab at bottom or the new brake pad retaining springs were left off ? Other or combination ?

SPRINGS help keep brake pads from touching rotor with brakes off .

Found this about placement of the sliding PINS . The sliding pins for the ACCENT below start at 58 seconds into video .

The PLACEMENT of the PINS into the brake pad mounting brackets starts at 2:29 in the video .

Placed in UPPER bore ( Top )

Placed in LOWER bore ( Bottom )

Found this about placement of the sliding PINS . The sliding pins like those pictured above start at 58 seconds into video .

Finally a guy who stops talking "top" or "bottom" (despite video title) and explains leading and trailing. Top or bottom is irrelevant-- or at least relative

Is this even a thing? On pads I’ve done, the wear tab can be clipped on to either end of the pad. I’ve never seen directional pads? Or maybe I have and didn’t recognize??

I know on the 2015 f150s the inboard and outboard brake bads are slightly differently

I know because I put a set on backwards not paying attention the slight difference and one pad wore down quickly/prematurely

the pads i bought online weren't marked

the new carquest pads i put on were actually marked inner and outer, and if you looked at the plate for the pads there were 2 small ears while the other 2 didn't have them so something was hanging up on the caliper and putting more pressure on the outer pad thus it wore much faster.

I've never come across that with any other vehicle, usually all 4 pads were the same.

so i'm guessing there are several vehicles out there where the pad position is specific

Found this . These directions are for the front brakes . I'll put my belief in the manufacturer and its engineers .

Calipers can be positioned toward front bumper or rear bumper relative to the axel. This will change location of leading and trailing side of the pad.

Yeah I think there are a small set of knobs on one side and a small set of knobs elsewhere on the other. If you get it wrong it wears weird and uneven. Same for my ford flex.

The same applies for the '18 HYUNDAI Accent replacement of the front brake pads and rotors . Placement of the Sliding PIN with Rubber Bushing in the bottom of BRACKET at 7:51 . Explains Why the PAD with WEAR Indicator needs to be at TOP in the bracket at 9:51 .



Rear brake pads and rotors of '18 Elantra . The '18 > '22 Accent SEL and LIMITED have same rear brakes . SE is drums and shoes .
Talks of Sliding PINS at 5:02 and the REASON for the placement of the brake pads with the WEAR indicators at 8:28 .

Soooo.....have you corrected your issue yet?

I put a set of rears on backwards on my dad’s Subaru once.

They worked just fine right until there was zero pad left because the squealer snapped off and didn’t give any warning.
