Hello guys! I heard some weird noise coming from the right rear everytime I hit the brake. Then I went to auto repair shop to check out the problem. The guy told me that the weird noise is caused by the aftermarket brake pad. He told me to change to brake pad to original Nissan one. He wanted to charge me 120 dollars for the rear pads. He said that may solve the weird noise problem. Any comments are welcome. Thank you.

 

I can get you the dealer rear pads for ~ $60. or some Hawk pads for the same. let me know if you need them. cheap aftermarket pads will make noise sometimes.

 

I have had Raybestos ceramics on my rears for 4 years and no issues at all!! Try giving it a shot, FYI, I replaced my fronts with the same ceramics, giving it the break in period and after 200 miles, it is as good as my Hawk HPS that was there on it earlier.

 

Buy a set of Nissan pad shims and install them. The problem is vibration, not the pad itself. Stupid mechanics throw away the shims, when in fact they are very necessary.

Always get the expensive one. I find that they are much better. Or from the dealer but I found that the best ones from NAPA are better than dealer sometimes I just got a max and I had a honda and that is where I found out this. The last person to have this car got cheap pads and they are making a bit of noise too I am going to be replacing mine shotly.

 

don't let anyone touch your brakes... do them yourself. Get good pads and shims and put them on yourself, and it will cost you way under 100 bucks (for rears only). Afterwards go out to a road with no traffic and bed them in real well.

 

Is it even possible to bed in rear pads? I wouldn't think they would get hot enough.

 

Thats where the parking brake comes into play.

 

well... it's not that important for rear brakes anyway. Front brakes do 80% of the stopping. I wouldn't worry too much about bedding in the rears. They should break in on their own as you drive.

 

you shouldnt worry about "bedding in" the fronts either. all a myth.

 

Did they explain how the rear pads are causing the problem? You can install any pads that will fit in the rear and they will work. How well they work is another issues but they will still work.

I would get a 2nd opinion.

The noise you hear in the rear occurs when you apply the brakes?


you are wrong.

 

you are right. new pads will nev er wear down to an even surface with the rotor without a driver speeding up and slowing down like an idiot.

thats why all shops get in your car and "bed them in" before you come and pick it up after a pad change.

 

Do some research on bedding in brakes and then post back.

yea cause all shops always do a great job on peoples cars

 

That's not what bedding in is about, it's about getting the pads and rotors hot enough to transfer the brake pad material evenly to the rotor.

 

There's a group deal on brake pads and Brembo rotors in the group deal section. Time to do it up right

 

Few things wrong in this thread:

Bedding IS Important, just because 4 million retards dont do it, doesnt mean its not imporant...

Fronts do ~60% of braking.


Also why are the shims so important?

 

Shims dampen and stop vibration.

I think the bedding thing is pretty much a waste of time on OEM type pads.

on any pad. this isnt NASCAR and pad technology has changed considerably over time. I also wonder, if you park your car for say a week and you get that nice layer of rust on the rotors, does one "rebed" the pads since the "transferred pad material" has now rusted off? or if one goes through excessive braking to the point where the pads begin to burn, do you "rebed" them since that thin layer of "transerred pad material" has obviously burned off.

 

Street pads are much, much softer than the rotors. They 'bed in' very quickly, unless the rotors are bad. They operate at low temps and as such they tend to operate by mechanical wear and friction. So bedding in a street pad is nothing more than the profiles wearing in to match each other exactly. The proof is that you'll see your cast iron rotor pick up rust - if there was a transfer going on, the cast iron would be sealed by brake pad material. But that hasn't happened - the rotor surface rusts instantly.

Track pads are much harder and operate more based on getting to extremely high temps and transferring some material to the rotor. Then in operation, the adhesive friction between the pad and transferred layer are what create most of the friction. The bedding in process is about building up enough heat to get the transfer layer started and establish proper adhesive friction.

Really, seriously, you should consider whether you understand this subject enough to refute others.
