Rebuilt Q45 calipers

[wmdavis007]

I finally decided to finish rebuilding my Q45 front calipers so I can put them on this weekend. I cleaned them in my buddy's parts washer, replaced all the seals and boots (Q45 caliper rebuild kit), got a set of Speed Bleeders, and replaced the brake pad holders. I also painted them with some Dupli-Color red caliper paint. Here are a few pics of them:

I've been looking at that combo as well.. I just put 18" on tonight and am teetering between that and Z32 upgrade. I need more rotor to fill the space. I like the color too. I always think calipers should pop with a nice color, but not one that's too bright (read: yellow) cause they look like crap too quick. Are you gonna upgrade the rears as well? I'd like to see what they look like on the car. Could you post a few pics when you put em on?

[wmdavis007]

Yeah I think I'll upgrade the rear calipers later on. I really wanted to get the calipers powder coated but the shipping was way too high. I like the color of the red Dupli-Color caliper paint...it's a nice dark red. I'll take some pics when I do the install. I also got a set of PBR brake pads and a set of drilled and slotted rotors from 88rotors.com. I had them drilled for 4 lug too. Oh yeah, got a set of stainless steel braided brake lines too.

Nicely done.

If you're shopping for a cheap upgrade, go as big as you can. What I mean is that if you've got some J30 or Q45 calipers laying around, toss them on - with properly sized rotors of course. If you don't have anything laying around, you might as well just pick up some Z units.

I've got the Z brakes on the front of my vert with the 17/16" master cylinder. Between the brake upgrade and the coilovers, it's a toss-up for best mod I've ever made to the car (yet). If I could go back and do it over though, I should have probably went with the 1" MC instead. I'm still rocking the stock rear calipers, so maybe when/if I get around to putting the Z brakes on the back, it won't be so bad...

Just felt like sharing.

Dex, did you keep the stock rotors on the z brakes? nice job on the calipers!!!

[DeXteR]

No way. Z rotors re-punched for the 4-lug.

Braking bias way off please? Haha, I have heard that 15/16 is the best choice for Z brakes front, stock rear.

I got my rebuild kit from RockAuto.com. BECK/ARNLEY Part # 0717831, they are discontinued now but they still have 4 in stock. The kit cost $12.02. The piston boots are a pain in the a$$ to put on, just take your time...took me about an hour to get them all on...last one took about 30 mins . Still haven't installed them on my car cause I was busy with my wedding and work but they will be installed soon. I would suggest getting SS braided hoses while you do the upgrade. You can get them at http://www.splparts.com/main4/main/default.htm for $45 a pair (look under Silvia 89-94, order 10mm banjo). I also got Speed Bleeders from them to make it a little easier so I can bleed them solo.

yeah thanks for the tips.. well i guess the people at my local auto zone are idiots they said that they don't carry them... but i went to an other auto zone and they had them in stock.. well i cleaned them.. put the seals in and everything just having trouble putting the dust boot on with the piston in place

[wmdavis007]

.. well i guess the people at my local auto zone are idiots they said that they don't carry them...

You said it!! I worked in a private owned auto parts store for about 6 years and found that most people that work at larger chain parts stores like Auto Zone, Advance Auto, etc...don't know a master cylinder from a starter...not to offend anyone that may work at one of these establishments I said.."most people" not all. I have a great local parts store I can go to...of course I know the owner and all but two of the guys that work there...and I get a discount .

Trick is... you have to push the pistons out a bit. It's very hard to replace boots when pistons are all the way in. There are 2 ways to push the pistons out. Before disconnect the calipers from your car, you can remove just the pads and press the pedal to push the pistons out a little bit. Or you can use air compressor to push the pistons out when they are completely out of the car. If they are out to much, you can use clamp wrench to push them in.

lucky i only got auto zone and napa... its better than auto zone but cost a more but dont carry as much stuff at auto zoneima have another crack at it again with the boots.. since its taking my q45 rotors 3 weeks to come in when the shop is only 5 hours away

Thanks for the helps guys

You can't compare generic kit and Nissn OEM kit. I've seen both z32 rebuilding kits and OEM kit was much better in quality. Get OEM kit if it's available. It'll last longer too.

I wouldn't really call the BECK/ARNLEY rebuild kit "generic"...it's very good quality, but if I had a local Infiniti dealer I would have tried to get an OEM kit.

You can get the OEM kit here: http://www.trademotion.com/par...gid=0 It's double the price of the BECK/ARNLEY kit.
