MX83 Drift Caliper Bracket

Recommended Posts

Yes, gordo. I'll take pictures to confirm it later. couldnt be more than .150" off

 

The problem with the honda crap, is that there are so many different calipers for that stupid honda civic, 3 different calipers (that i know up) with the same bolt location (that's where it fucks up)

 

I had taken the bracket to the junk yard with me and just found "said honda." I took the caliper off and it fit my bracket, so i figured im good to go.. that was a nope!

 

oh and if you get a 5/8" master... good fucking luck locking up your wheels..

I have had this bracket set up on my car for over two years.

I first used a set of 85 base model Honda calipers with pads from a junk yard and the pads were so fucked it took extra pressure to engage which eventually blew out one of the calipers.

I then ordered a set of new 1986 Honda DX fronts and vatozone brand pads that function really well.

Yeah I have some pad that is not contacting the rotor, but still more surface area than z32 rear pads touch. They bite well with a 3/4 master.

Just my experience.

Pad area doesn't effect much except life.

And a larger pad actually will bite less than a smaller pad.

Actual braking torque is a result of pounds of force on the pad, and swept area.

 

So, are the honda caliper pistons larger than the Z32 pistons ?

The diameter is what determines force.

I am going to have to disagree with you Gordo. If that statement alone was true then changing out the pad material to a more aggressive compound wouldn't make a darn bit of difference.

To calculate how much friction is on two surface areas

you multiply surface area times pressure.

You should do a little more research on brake design, and the physics of friction........

Just saying.

Prove me wrong don't just pull the old blah blah blah.

Math doesn't lie.

Gordon's logic makes sense to me... calliper puts out x amount of force. If that goes into larger pad its more spread out and therefore less friction per cm^2, so in the end the total friction and braking is same overall...

 

Think about a three puck clutch... why the heck would those be a thing if your logic holds true.

i can see the logic in your argument, however;

Large trucks, heavy equipment even massive ships (yes boats) use drum breaks because of the contact patch and surface area they provide and require less pressure to enact friction.

The main reason for changing this method in cars and trucks is the disipation of heat.

If you compare the type of material used in a three puck clutch to a full face, there are extreme differences in the make up. Less organic material to save on flywheel wear with a full face.

Three pucks are very abrasive and destroy metal quickly.

Basic Engineering classes when I was in college discussed frictional masses, surface contact patches, surface area etc.

these were very basic problems and equations they give students using variables in material, and environments.

Bingo !

 

The only place this doesn't apply is on race tires, due to when they are up to temp, the surface isn't dry, but fluid,

so fluid adhesion comes into play.

I had to explain this to my tech school physics teacher many years ago, do to his claim that wide tires don't grip any better than narrow tires. But once he heard what makes wide tires work on a race car, he accepted it.

 

See, it isn't old age that makes me a sarcastic, pain in the ass, I've always been this way.........

This sucked for me also because wasted money on the wrong calipers... here's what i ordered from rock auto...(that works)

These are the calipers that Rich recommended and I ordered on Monday. They should be to me by the end of the week. (Can't beat that price for fully loaded calipers!) Evidently these have the most percentage of pad on the rotor out of all the 80's civic options. The other issue that I was running into is the junk yard calipers I found also contact the stock wheels preventing me from using them as spares if need be. Hopefully I can gain a little extra wheel clearance with these

 

 

The science in this thread is good, I have always believed that when it comes to brakes, in general, bigger is always better. The science of why that isn't always true fascinated me though. If the caliper clamping pressure makes the same or better result than pad size, by the same logic wouldn't upgrading the bore size of the e-brake master cylinder have a vastly greater effect on the performance of the setup than any variation of Honda caliper or pad size?

Too much pressure from the smaller master might do that.

There, fixed.

Larger master would put out less pressure than a smaller one, with the same hand pressure.

My Honda calipers hang off my my rotors too and have maybe like 50-60% pad contact but it locks good and hard everytime with a 3/4" master and random cheapy pads.
