I've changed rotors and pads before, it was no problem.

But now I have 6th gen calipers and rotors, and I've never changed calipers before.

Are there any special tools that I'm going to need? (I seem to recall reading something about a flare-end wrench?) The part I'm specifically confused about is how to properly disconnect/reconnect the brake lines. Anybody have a how-to or just general directions on how to do it?

Also, I want to do a full brake system flush. What is the proper order again? And will I need any special tools for that too? Also, what kind of brake fluid should I flush with?

Thanks all!

17 and 19mm closed ended wrenchs for the two big bolts as well at a 10mm or 12mm for the brake line, thats abotu it, oh and new brake fluid, might as well change that while ur at it.

 

and bleed the brakes...

 

Well if you don't have the right flare wrenches for the brake lines. I carefully clamp on Vice Grips onto small side. It grips the line pretty well and there is very minimal marking to the line. If you use a normal flare end wrench, you stand a pretty good chance at ruining the soft fitting.

 

Not trying to hijack but when replacing rotors and pads do you have to also replace the brake kit (brackets and whatnot) from Nissan? I remember one time I had my brakes replaced the guys at the shop had me come back with the new brake kit to finish off th brakes.

 

brake kit huh? unless u really wore ur brakes down to the point where the caliper is being pulled or bent or soemthing like that i se no reason to replac ethe bracket, i added brackets to allow my 04 conversion but thats just an add on piece.

btw check ur blinker fluid it could be low.

 

 

Thanks guys, that's what I needed to know.

 

Well, the last time I had my brakes done they replaced the front pads and turned the rotors. When they reinstalled the brakes the car made this incredible scraping/screeching sound. I inspected the brakes and the bracket (clip) was scraping the rotor and it was even worse when the brake was applied. The service manager said the clips were bent and caused the scraping. I bought the new clips and they replaced them and the problem was fixed.

Here's a pic of how scraped the freshly turned rotor was. It was worse on the other one and even worse on the inside.



Oh and my blinker fluid was low, thanks!

 

just another reminder, i had all my calipers removed, my tire place broke some of my studs off the tire started to wobble and so sdid the rotor and it messed up a caliper. so i took them all off for paint as well as replace the bad one.

i had to bleed several times in order to get all the air out, farthest from the master to closest. and it worked much better to have the car running, not just on acc, but actually running.

 

Use synthetic break fluid. It is cheap for brakes and it will pay off in the end.

 

I actually ended up going home this weekend and taking it to a shop run by the folks who used to run the Infiniti service dept. in town. They installed the new rotors and calipers, flushed the hydraulic system, and bled the brakes.

Is it normal to expect the pedal feel to be different with the newer, larger rotors and calipers? Before, as soon as I pushed the brake pedal I'd start to feel resistance and braking. Now, I push it, and the pedal travels farther, with less resistance, but there's still braking. I push in harder and it stops faster.

I know what you're thinking - air in the system - but they bled the brakes twice. In fact, when I first picked it up the pedal was horrible, it felt like there was a giant bubble in the system. I took it back, had them bleed it again - I watched, they did it in the right order, and they didn't get any air out. Took it back down, went for a test drive, and then the pedal was back, but this time with the feel that I described. I've driven a great deal today, and the pedal has never felt spongy, doesn't feel like there's air, it just feels different. Is that normal?

The techs hypothesized that maybe the metering valve got stuck or something, does that sound right?
