I have been meaning to post this DIY for few weeks now. I did this couple weeks ago. Those of you who go to track regularly, I'm sure you've done this many times. I still decided to post this perhaps it'll help someone or answer a question they might have about power bleeding. This was my very first time using Motive Power Bleeder.

It's recommended that you change your brake fluid every 2 years or 24 months, if you drive your car on the road (no track). If you drive on the track, the interval becomes much quicker (unless you're using Castrol SRF which is 18 months). You should bleed your brake before doing HPDE at the track. Brake fluid has a tendency to absorb moisture/water over time. So the longer you wait, the more water you'll have in your brake fluid(which is not good). I was actually surprised how easy it was to do this and from this point on, I'll change it every year (unless I'm attending a lot of HPDE )

If you have any question or suggestion or if you see I have posted wrong info, PLEASE post your input. I'm ALWAYS open for suggestion:

I have posted the video in Post 2. Don't forget to check it out as some steps are easier to see then follow via text.

What you'll Need:

1. 0117 Black Label Ford / Import 3-Tab Power Bleeder

I went with the black label because of the quality. Bleeder reservoir cap is made from custom machined aluminum. Comes with 6 feet of high grade poly urethane tubing. I think it's def worth paying extra $10-$12 from the regular plastic cap and shorter flimsy piping. Just my It has a range of 5-30 PSI which should be more than enough for your Z.

PS: Please ignore the dirt here and there. This bleeder floated in Sandy water . But I have thoroughly cleaned it with denatured alcohol. I also used synthetic grease to grease up the pump and even ran some fresh out of bottle clean dot 3 before I used Motul through it for the Z .



2. Longacre Brake Bottle Bleeder

I must give credit to Mike Bonnani (used to own Double Down Motorsports). I remember him using this for his bleed. What makes this better than other is because we have two bleeder nipples on our caliper. So you can hook both pipes up and not have to worry about taking off anything until WHOLE caliper is done. It was very snug fit and perfect for the job



3. Motul RBF600 Racing Brake Fluid 1/2 Liter (500 ml)

I initially went with ATE blue but after hearing some reviews about staining the brake lines and people having problem differentiating the orange ATE during next bleed (after a year) etc, I went with Motul. These fluids held up amazing during a HDPE I attended couple weeks ago. Also, if your car is under warranty, it's probably better to have Motul than the ATE blue because your service adviser may give you trouble(stink eye ) if there's any brake related issue that need to be fixed under warranty. With Motul, he probably won't be able to tell . Also, let not forget, it's Motul! I think right after SRF, is it safe to say it's Motul that is most popular among everyday track guys? (non professional racing)



4. Turkey baster or surgical bulb syringe (Dover) or 60 cc piston syringe.

These are just to suck out old fluid from the reservoir. I personally like the 60 cc syringe but turkey baster is fine too.



5. 10 mm wrench to loosen the bleed bolt and any other tools (jack, breaker bar etc) to remove the wheels.






STEP 1:
Locate brake/clutch fluid reservoir area. They are located on the Left side of the vehicle next to windshield (driver side).




STEP 2:
Find the brake fluid reservoir.




STEP 3:
Remove the thin filter inside the brake fluid reservoir and put it aside. Now use the Turkey baster to suck out as much old dirty fluid as you can. Notice my fluid is pretty clean. I used to suck out old fluid from reservoir every 6 months with the 60 cc syringe and replace with Nissan's dot 3 from dealer. I did what I could to keep things clean







STEP 4:
Open one of the Motul RBF 600 bottle and pour some fresh fluid in the reservoir ( to the max line).



STEP 5:
Now put the Motive Power Bleeder Cap on the brake reservoir. If you have the black label, the fit is VERY snug. The cap will not connect to your reservoir if you push and twist at the same time. Follow these instructions from Motive Website:
Note: this cap can be difficult to connect to the reservoir, it is designed for a tight seal, attaching the cap is a three step process
1) Align tabs with cutouts on reservoir
2) Push cap down until it seats. You may need to rock it to have it seat.
3) Twist to seal.





STEP 6: (watch video)
Close the Motive Bleeder Container (no fluid inside yet) and start pumping the bottle. You're doing this to check for leaks. Pump until the psi gauge show at least 10 psi. If no leak, release the pressure and open the container.





STEP 7: (video)
Pour 2 bottles of Motul RBF 600 synthetic brake fluid. I poured 2.5 bottles in the video but I had about .5 bottle left in the container at the end.



STEP 8: (video)
Close the Motive Bleeder tight and start pumping. Bring the psi of the container up to 15 psi. I know some of you do it at lower psi but I remember reading somewhere we need at least 13 psi to open abs valve? Anyhow, 15 psi worked great for me. My results were superb so I'm sticking with it.



STEP 9:
Remove the right rear wheel (passenger rear wheel). This is the furthest caliper from the master cylinder/brake reservoir. I'm not sure if this furthest-first, closest-last method is still effective but I'll do it anyway. Keep thing simple. Find both brake bleeder nipples on the caliper.









Step 10
Attach the Longacre brake bleeder bottle piping to each caliper bleeder nipples. Remove the rubber cover first. It should look like this:


Outer







It should look like this



STEP 11: (video)
Go check real quick to see if you're still at 15 psi in the bleeder. If not, bring it up to 15. It shouldn't go down much. Open the Longacre bottle lid(white) slightly so that air can pass (also loosen the black valve on the bottle bleeder pipe above the bottle lid). Now slowly open up OUTER brake caliper bleeder first. I followed Chris's advice. Let the bubbles, metal fragments, dirty old brake fluid etc go into the bottle. I think I saw most crap from this rear right bleeder nipples. Once you see that old fluid is starting to change color and turning into Motul deep golden color, tighten/close the bleeder bolt.





STEP 12:
Now open the inner bleeder nipple on the same caliper and let the dirty fluid go to the Longacre bottle. Once you can see that Motul color fresh fluid started to come in (no bubbles visible), close the bleeder bolt. Detach the Longacre bleeder bottle pipes from both bleed nipples and put the rubber cover on them. You're done with this wheel. Put the wheel back on.



STEP 13
Check and make sure you're still maintaining 15 psi. I checked after each bleed and made sure my psi didn't drop below 15. Now repeat step 9 thru 13 for rear left caliper, then front right caliper(passenger) and finally front left caliper (driver).



Once all 4 caliper's are done, slowly release the pressure from the Motive bleeder. Carefully open the reservoir cap and make sure brake fluid doesn't drip into paint. It's very acidic and will eat through clear coat. Now, pour some Motul fluid into the reservoir and fill it to the appropriate fill line (between min and max). If your caliper saw a drop or two of brake fluid, use all purpose cleaner(Adams my favorite) to remove it.

TIP: if you have some left over motul, suck out the clutch reservoir and pour some fresh Motul in there instead of throwing away bc you rather NOT use opened brake fluid 6-12 months from now.

That's it! you've just bleed your brake fluid. It's so easy and didn't even take me 2 hours. I did go to a HPDE in freezing 29 degrees and brakes held up fine. So I'm not sure how the result would have been if it was 80 degrees out but I think it would be similar. Pedal feel was great. very linear and predictable feel and will throw your passenger into dash if slammed hard (well thanks to Stoptech pads and rotors which I'm working on the DIY ) I am glad I finally did it. It's been almost 4 year with my old brake fluid! Hope you enjoy the video as well where I can show you in more detail.



Thank you
