I get this really annoying vibration when i step on my brakes, it sucks! It happens at any speed, even 5mph and its rythmic, which makes me think its warped rotors. I think somebody here on the forums said it could also be the calipers??? How possible is that? I'll be getting new rotors soon, i just want to see how many people had problems with their calipers. I need an excuse for 300ZX TT brakes.....

 

Theres a fair chance it could be the calipers. Change the rotors and pads first. Check the rubber sleeve that covers the caliper piston if it is torn, you should change it if it is torn.

 

I dont see what would cause the rotors to do that...I personally think it is warped rotors and maybe ur pads, but it just seems logical that it would be ur rotors, get some new ones, and if it doesnt fix ur problem...I guess you can say I was wrong.

 

Yeah I'll be changing the rotors pretty soon, once the weather gets a little better. The pads are practically new so i don't think it's that. Thanks for the replies.

 

i just did the brakes on mine i noticed that the calipers were sticking, i had the same problem as you as you braked the car shuddered and pulled to one side,sure enough both calipers were sticking.
so replace the rotors and check your calipers for sticking. if they are sticking they will warp the rotors from getting so hot ,especially nissan factory rotors
if they get wet when they are hot instant warpage.

 

I have the same problem, I've already changed my rear brakes about 12k miles ago with raybestos premium roters and QS pads. its time for a front replacement!

fiddyonefiddy, this might be a silly question, but how do you check for sticky calipers? Can you try to be as specific and thorough as possible in your explanation please?

(only way i think to check, is to hit the brakes once the calipers are off. but im not sure i'll know the actual difference in 'stickyness' compared to a smoothly operating caliper. is it that it either sticks or it doesnt, or are there degrees of stickyness? hehe. i'd appreciate your input.)

 

My car was making the same kinds of noises. I bought new rotors and pads. As i was installing the caliper, I noticed one of my calipers was frozen. Under the ruber boot was tons of rust. I had to go get both front calipers rebuilt and now they work great. So, make sure you check inside that rubber boot too!

 

Yeah save up for some springs too. your car looks like a 4x4 rallye racer

 

if you change the rotors youll have to change the pads as well. the pads may have worn down to the contours of the warped rotor making the surface uneven. using old pads on new rotors will wear down the rotor unevenly. so obviously change both at the same time when you have the chance.
