Galant Brake Upgrade (Big Brake Kit!)
« Reply #15 on: September 19, 2011, 04:33:00 PM »

I'm just out of my element, I guess. I grew up in the Pro-Street era where a s#!t load of torque was transferred from a hub to a rim to the point the tire was screwed to the rim to keep it from spinning on it. All my spacers are machined to accept the original hub's center support and also has it's face machined to support the rim. I was a frame tech for over 30 years and I have seen when "do it at your own risk" fails. I have seen cars improperly modified for everything from lowering and hydraulic suspension gone wrong to cars completely collapsing in a bad way with people shredded inside.

Mr. PC,  What material do you machine your spacers from?

I would have to ask my machinist what he uses but they are steel because of the 2" offset I use, the spacers are fit with their own studs. I've only done spacers for my Sonoma 4dr. Seems the rear end is WAY too narrow. Noticed it the first time I drove it in the snow and saw the rear tire imprint completely between the front tire imprint. I put steel rims on it for the winter and used 2wd rims on the back. The two inch difference put the tires perfectly inline with the front and looks a whole lot better in the wheel opening. Thus, to use the factory alloy rims which are all 4wd rims, I had my machinist create the spacers. In the Pro-Street days, we narrowed rear ends to fit our application. We then used rim off-set to center the tires in the wheel-well.

I just finished doing this upgrade to my car today. I got everything from a local parts store. I got the calipers from a 95 escort and I told them it had 14 inch wheels so the would give me the right caliper.  I had to turn my hubs down .540 in to get the rotors to slide over nicely with just a little play.  I didn't have to grind the caliper throat at all to get the 22v 14 calipers on. The only adaption I made to the brake lines was to cut off the little tab because it didn't line up on the new calipers.  I even used the same banjo bolts!!!  The stopping power with this upgrade is significantly better and was needed with all the mods I've done. Figured I'd add this info as its all stuff I learned from actually doing it as opposed to reading about it on here!

Hey guys - In a Nov. 22, 2011 post in this thread, "newboyracer" said he had to "turn my hubs down .540 in to get it to get the rotors to slide over..."  What does this mean?

It means he machined .540 inches from the original outside diameter to get the rotor to fit

Welcome to the forum, by the way!!

Glad to be here!  Waaaaayyyyy out of my element, but learning as I go.  So the 95 Escort caliper is a clean fit for the big brake upgrade?  also, in your lead-off post, I think you said the front hubs require machining.  Do the rear hubs require machining as well?  Or do you only do this brake upfit on the fronts?

This upgrade is fitted to the fronts only. In the rear, the rotor is part of the bearing assembly & hub itself, making upgrades very difficult.

Yes, calipers for the 95 escort will fit.

Just checking around - is this a possible rotor candidate?  (1990 Infiniti M30).  Centric 121.42013 Disc Brake Rotor, Rear.

Not at all for the front, it's a solid unvented rear rotor, you do not want that on the front of your car.

The one you posted from carpartsdiscount appears to be the correct rotor

To put in the "for what its worth" category.  The folks over at the mazda site say the upgrade does not require upsizing to a 15" (or larger) wheel.  They say it works fine on a stock 14" wheel.

Yep "14 is fine.  Good Note!

Any less offset than a couple mm and you'll be needing spacers.
