My car brakes pads have been grinding when coming to a complete stop. The noise is not usual as the front pads only have 28k miles on them and i am used to getting 40k miles . I do lots of in city drving and taking turns but this cant be the cause as this is how i always drive. I took the front tires off to see. The outside pads shows half the normal thickness but when looking at the front of the inner pads (without removing any parts), i can only see a thin sliver of it. It doe not help that the brake wear sensor wire was never attached to one of the front brakes. My car-328 e46- has 200k miles and the brake caliper has never been replaced, im thinking it is this. Any thoughts and what am i replacing and how much? Can the shop just replace the inner pads and front calipers? Thanks.

the "non cylinder" pad will wear faster. however it should be extremely minimal. try cleaning and inspecting your guide pins. they might need to be replaced. i also think there's bushings that can be replaced that hold the guide pins. those might need replaced.
either way, i think its the pins. the caliper should slightly release when not braking but cannot if the pins stick.

OP...yes, a shop could just replace inner pad, but they'd be a shop you wouldn't want to go to again! You can't buy one pad...they'd put both on.
If it's the inner pad, sounds like your caliper might be the issue. There's a seal you'll see around the piston behind the inner pad. I bet you'll see damage to it...and probably some rust on the piston. They can be rebuilt with a $20 kit, the piston cleaned off carefully, but for under $100 you can get a rebuilt caliper.
One your pad wears down all the way, and the metal backing touches your rotor, they're done...they'll usually last two pad sets.
Sounds like your piston isn't retracting all the way. Which also means that that rotor will be getting very hot, so you'd be losing a bit of braking power too just from that.
Get to this pretty soon...or it was nice knowing you!

When im about to stop over a hump or dip, the front brakes sound like they are grinding. Its like this for 3 weeks. I had my car for 14 years since new; i also had my indie shop do my car works, that i could not do. The front calibers looks old and if i want an inspection done, i have my shop do it. About $400 for new front pads and rotors and $500 for fronts calibers are not something i look forward to.
Remanned calipers probably only $60-70 each. Rotors $100 an axle...pads $50 an axle. Reading fanatic diys on brakes until you puke...priceless.
Get new rubber brake hoses too if doing calipers at your mileage. You'll look forward to diying less, but once you survive it, you'll feel great and pocket $100's

Thanks guys. As i am writing this at this coffee shop, a big sign across the street and in my face says " Mercedes and BMW service". I like this to be as cheap as possible as i think i did not get my money worth. I put off the diy as im too lazy in the past to get the proper lift jack to do it. Guess it may be time .
After taking my car to my indie shop and looking underneath the car, it turns out i have a good 6 to 12 months of inner front brake pads left leftso that relieve me of my primary safety concern. It had nothing to do with the brake system supposively. . I took the mechanic for a drive and we were not able to duplicate my experience. With a new front brake sensor installed , after the current one went loose and new brakes to be done much later on, this is acceptable.
