Hello guys,

My dad drives 1999 GXE and he has been having some problems with his rear
brakes. He had rear brake pads replaced after original ones were worn out. After Nissan
replaced his brakes, about a 6 month later, very strange sound started coming from the
rear of the car when moving slowly. Like groaning sound.
So he didn't think anything about it until one time he took of the tires to do the rotation
and he noticed that both rear pads are almost gone and rear rotor are all messed up.
He went to Nissan and after many arguments they agreed to do it for free, because
my dad was saying that the pads couldn't wear out that fast.
So they gave him new rear pads and rotors. All good, he thought.

Now after about 2 months the same sound came back, my dad took the rear wheels off and
saw that on one side same thing is happening as before, pad is worn out and rotor is all messed up. He tried turning the wheel while on jack stands and the wheel would almost not move. The other wheel on another side was turning fine.
So what he is thinking that pad is always in the contact with the rotor, he went back to Nissan
and they are saying that everything is fine. So he is not sure what to do now??

I was just thinking if anybody else had similar problem or know what can be causing his problem with rear brakes.
Can the caliper be messed up, etc?

Thanks.

 

sounds like the caliper got locked up on the rotor due to improper installation. i suggest taking off the caliper assembly, get some brake cleaner and clean it, then put it back in. here's the tricky part, if you have to FORCE the caliper in (aka hammer it, or pushing it extremely hard), then it'll cause uneven wear on the brake pads and produces weird noises while rolling. if that's the problem, remove the caliper again, step on the brake pedal like 20 times or so (release brake line pressure) and try to slide the caliper in again. if it slides in very smoothly without too much force, then your problem should be solved.

if that didn't help...just post away

that's the 4th gen brake disassembly instruction. although it says "front", but the rear is similar.

 

What could've happend also is the rear pads have a small stub on them. Make sure that stub falls into the piston, if not it will ride on the piston itself instead of the hole its supposed to fall into. Its hard to explain but when you look at the piston it has 4 small grooves. Make sure one of the grooves is facing directly downwards and when you put the pad in, it should fall right into place. If not, the pad will ride the piston and make your wheel stick. I noticed a very faint groaning noise at low speeds and after very little braking, I would check the rear pads and one side would be warm and the other extremely hot from sticking to the rotor.


Try looking into that first before going to replace the calipers and spend $$$. It happened to me.

 

What are you talking about forcing the caliper in? I hope you dont mean to push the piston in. Theres a special tool that you use to screw the piston back into place. It looks like a cube with ***** on it, you attach it to a rachet and the piston screws back into the caliper.

 

no that's not what i'm talking about.

yea.

 

Thanks guys.

I will let my dad know and we will take a look at rear brakes with him to check for the
things you mentioned.

 

Okay just making sure

Your never gonna get it in by giving it a good beat down

 

When you say remove the caliper and step on the brake pedal 20 times,, wouldn't piston
fall out if you do that?
