Galant Brake Upgrade (Big Brake Kit!)
« on: August 11, 2010, 07:10:00 PM »

Front hubs require machining (easiest) or fairly precise hand-grinding for the Galant rotors to fit. The hub gets machined so the hat of the rotor fits over the hub.

You need to take apart the stock hub setup, remove the old brake rotor, drive out the old lug studs & install new longer studs. Its a good time to replace your bearings and seals.

The proper rotors to use are 89.5 Galant rotors - 266mm (10 15/32) Please note there are also 256mm (too small) and 276mm rotors (the 276mm is the VR4 rotor. it requires too much grinding in the caliper throat and wont add any effective braking area)

The caliper needs to be ground out in the throat to clear the edge of the rotor. It does not need much with the 266mm rotors.

The Escort caliper will bolt right to the stock knuckle.

Use this as a general guide:  http://323gtx.homestead.com/brakes.html

And heres a comparison pic, stock vs. Galant upgrade

 

Figured I'd throw this info up as a sticky.

So basically you're saying buy those korean rotors from KVR, via corksport. $80

I could probably get a nicer set of Centrics for less, using a part number that autopart stores recognize.  Can get these for roughly $25.

My question is are these the correct rotors.

266mm is what the guide said right?

The difference is the expensive rotors are slotted and zinc coated. Nothing I really care about...

My point is that if I go into an autozone, napa, or what have you and ask for M1332 rotors, they'll tell me there is no such thing.  It's not a recognized part number.  The rotors listed for the 1989 galant are 120.46014, Centric is a globally recognized brand.  Say if Corksport or whoever drops those KVR rotors, there's no interchange for that number to a brand name rotor.  But brands like Centric, Raybestos, Brembo, and Bendix are recognized brands that any auto-parts store can interchange part numbers from if they don't have that particular brand.

I dont have the particular part numbers. I went into my local parts store and gave them the info, and made sure the measurement was correct and ordered them, had them a few days later. There were a few brands to choose from I went for something reasonably priced. I didn't need any part numbers i just told them the car I needed them for...

Ya, they can tell you the diameter of the rotor..thats how you know if you got the right one!

The center of the hub extends out to center the rim on it and transfer the weight & torque from the rim to the hub. By adding the rotor to the outside, you space the rim off the hub and the center of the hub doesn't reach the rim. Thus, the load of the rim isn't carried by the hub, it is carried by the studs and lug nuts. These are only engineered to hold the rim to the hub and not carry the weight and torque of the vehicle. Thus, doing this "upgrade" puts you in danger of a stud failure and a wheel coming off.

I'm aware of what a "Hubcentric" wheel is. This is a hotly debated topic across the internet, feel free to research it - plenty of info out there. Most people with aftermarket wheels are not hubcentric anymore, either. It's generally regarded as a "do so at your own risk, but it's unlikely you'll have a problem"

You could have hubcentric ring adapters made up if you wanted.

FWIW: I've put on over 20,000 miles since doing this upgrade, zero issues whatsoever. There have been some GTX guys running this upgrade since the early 2000's as well, when this upgrade was first "invented"

Sounds like my old tire guy who told me he couldn't fit my lugcentric wheels without a hub adapter.
