Ok here's the deal. About 2 weeks ago I had new brake pads put on all the way around, I got new front rotors and had my rear rotors turned. At first the brakes were really squealy and weren't stopping that great. So I gave it about a week and the squealing has gone away and my stopping power has greatly increased. No complaints there.

Where I do have my complaint is this. When I park on an Incline (like my driveway) and park my car overnight, when I get in my car in the morning and I sit in my car, the car rolls backwards. Yes I have my car in Park all the way and Yes my ebrake is all the way up (and no I don't weigh a ton!) It will roll backwards until my transmission locks in (just like it would if I parked & didn't pull up my ebrake). The other thing is when it does this my brakes make this horrible noise like the pad is grinding against the rotor.

Now I have taken my car back and my mechanic deglazed my rear rotors (because rust had set in them - it rained or I washed the car like a day after I got my brakes done) and they weren't working like they should. He adjusted my ebrake as much as he could, but since it isn't stretched out there isn't much more adjusting he can do to it.

I have still noticed even more braking power, however the only problem I still have is parking on steep inclines. It seems when it's warm outside and I park my car and say an hour or 2 later go back outside, all is good. My car doesn't roll backwards. I assume because my brakes are all warmed up still?

I guess my question is, with these types of brakes has anyone else had this problem, and does it really take this long for them to wear in completely with the rotors?

Sorry this is so long, I just wanted it to be detailed.

Thanks

 

I don't think it's a brakes problem.

If I'm reading your thread correctly, you're saying that your car rolls back a little after parking it for a while even though you have it in park and have the e-brake up.

I think there was a thread a while back with someone with the same problem.

Next time you park, try this: Park, put the shifter into Park, let off the brakes, then pull the e-brake. The next time you start the car, it shouldn't roll back.

 

I have Axxis Metal Masters with slotted rotors. I know the noise you are talking about when lightly braking on a hill. I believe the noise is the same for all semi-metallic pads though since it's basically metal on metal contact. After installing my pads I had to adjust my ebrake quite a bit as well, but I don't park on big hills so I've never really had a problem. The only other thing I can think about is a "tab" mentioned about the rear brakes. Supposedly there is a tab on each side of the pad that the caliper is supposed to fit around (or something like that). Other than that I can't think of anything that's wrong unless your ebrake cable is stretched out.

I know exactly what you are saying. However the reason I pull the ebrake before I let up off my brakes is so when I'm on an incline my tranny doesn't roll back and let the load of my engine rest on my motor mounts. I know that if I park and then let my car roll back and then use my ebrake it's not going to roll. Also it doesn't roll when I start my car, it rolls as soon as I sit in it ie: put pressure on the brake system.

The point is, with my ebrake on, my car shouldn't roll back. I never had this problem until I got my new brakes & rotors and now all of a sudden it's like my brakes aren't gripping properly.

 

I had semi-metallic brakes before and never had this problem.

I just don't think i'm going to get a response. Unless you guys actually hear & see what I'm talking about I know it's hard to diagnose.

 

You got that backwards. By doing the above you will have the weight of the vehicle sitting on the park pin in the transmission, causing a possible hard shift out of park. The reverse of what you said to do will eliminate that. Pull up the brake, allow the car to roll back slightly until the brake catches, then put the car in park. That will assure you a much easier shift out of park on a steep incline.

The problem this guy describes sounds as if his brakes, once cooled down, don't have the holding power to keep the car still. This may be possible with the Metal Master pads he's using. These pads do require a slightly longer warm up time before they grab. Not that that's a bad thing, but the downfall could be the lack of holding power once the pad and rotor are cold.

Although he's getting great braking performance with these pads once there all warmed up, (normal driving) apparently when there cold, they don't grab very good.

Another possible issue could be his rear calipers, the e-brake portion isn't applying enough pressure to secure the car. Perhaps a rebuild is due.

 

I'm a SHE...thanks :-) And you are correct about the Park Pin. Which is why I don't do it the way Clee described. I get hard shifts out of park. You've given the best answer yet. Kinda what I'm looking for....so I'm getting great braking power, however the Holding power when the brakes are Cold, isn't that great. This is exactly what I"m experiencing.


Thanks njmaxseltd

 

Well ... darn me ... I've been doing it wrong all this time.

And Sarah beat me to it ... she's a she ... unless she's hiding something from us.

 

LOL no trust me, I'm not hiding anything....



except that I'm now pregnant

LOL, cute Jeff

 

I understand 100%! I've had the same issues with my Metal masters, and never had the problem with the Axxis semi-metallic pads before.

I think it's what njmaxseltd stated. It's cause these brakes need some warm up time. When I leave my apartment, my brakes pretty much suck for the first two stop signs, but after that they are great. So lately I've been purposely pressing them a little harder right away.

 

Great! I'm glad I'm not going crazy then. I know what you mean about the first 2 stops. They suck, but after that it's fine. However I could drive all day long (get my brakes all nice & heated up).....park my car overnight, but it will still roll back when I sit down in my car and the pressure gets put on the brakes. I will take my car back to my mechanic in a month. That will give it plenty of time to break in and if it's still doing it I'll have him check my rear calipers....however I'm wondering if that's covered under Nissan Warranty (I have the 100K mile warranty). I'll have to check that.

 

Wooooo! Congrats!

 

Thank you

 

Your welcome Ms. Sarah
