quicker removal of 1st gen front rotors

Does anyone have a trick for speeding up the job of removing the front brake rotors on a 1st. Gen RX-7. I have ground down a 14 mm wrench to fit better behind the bracket that holds the caliper, but it is still a pain to get at it. Any ideas would be greatfully appreciated.

I found that if I pulled down on the top of the bracket after I took the top bolt out and move the bracket up and down it loosen the lower bolt so I could get an open end wernch in to remove it. I had to use some persuasion to get the bracket to move but once it did I had no problem getting the bolt out.

John,

That bolt is a PITA. I use a 14mm long box wrench and I wedge a square shafted Craftsman screwdriver behind it to hold it on. I am able to get the box wrench on far enough on that I can break it loose, and I then use the open end to spin it off.

When I put my brake ducts on I ground down the edge of the caliper mounting bracket so a box wrench would fit the bolt head. Only had to do this on the top bolt. I took off very little material on the bracket. It seems to work pretty good. I can change a rotor in about 15-20 minutes if everything else goes well.

Drive well.
 
Ditto to to the method used by Bill. Works great.

I remove the rear bolt from the bottom of the strut, loosen the front one, and wa-la rotate the assembly and use a socket on that nasty little bolt.

I too can change the rotor in ~15 minutes, although the first time on an aquired Rx7, often takes longer

I use an identical procedure; the last one took ~20 minutes including installing a new inner bearing. . . .

Go to Sears and buy a combination 12/14 mm OFFSET box end wrench. It has a 12mm 12 point box end on one side, a 14mm 12 point box end on the other. Each box end is offset ~1/2 inch from the handle. It fits right into the caliper bracket and gives your knuckles extra clearance. Also handy for those pesky drive shaft bolts!

Ding! (Lightbulb just turned on upstairs) That's why the calipers came off so quickly on my new RX! As I was removing them I was thinking "hmmmm, this is going awfully quick."

In my defence, the spacers were already installed when I bought the car.
