I just upgraded my front brakes on my GSR to Legend GS dual piston calipers and Prelude VTEC 11.1" rotors.

The stock brakes on my GSR had been pretty lame for some time now (warped and squeaky), then last week the right side caliper started sticking and making the car pull to that side so I figured it was time to replace them. Since I had to get new calipers and rotors I said why not and went for it.

I have tons of pics so i'll just start posting and adding captions as i go.

Taking off the old stuff:

of course those screws are stipped out, aren't they always?


drill time


Got 'em


The floor after using the hammer to get the old rotors off



The new stuff:

94+ Legend GS calipers - 2 pistons


Putting on the 4th Gen Prelude VTEC rotors re-drilled to 4x100 lug pattern (by me)




Stock warped 10" Integra rotor vs. new 11" Prelude rotor





The work:

In order to get the Legend calipers to clear the rotor you need to shave off approximately 3mm from the carrier bracket.

At first I decided to use my dremel




After breaking off about 6 grinding bits and not making much progress at all, I retired that idea


I was really bummed out a for a minute there but then I looked in my tool box and remembered something...

AIR TOOLS JACKASS!!!!

serious business bits


Grinding begins again and progress is made, the serious business kind



Piles of metal dust everywhere



Installation

after lots and lots of test fitting


checking clearances


and more grinding



The calipers were on and ready for bleeding


The rotors are painted where the pads don't make contact to prevent ugly surface rust



After bleeding, the wheels go back on


Back on the ground and sporting some new, bigger brakes.








And a couple to compare the before and after:

Stock


Legend/Prelude upgrade

Conclusion

Lots of work to get these on there, almost seems to not be worth it at times but once they are on, just looking at them is very rewarding.

But the real reward is once you try them out.

Overall they are worth the time and effort IMO. Stopping distance isn't reduced by too much over stock (in my case it was. My stock rotors and calipers were tired and ready to be replaced) but the real benefit to this set up is the reduced brake fade under repeated heavy braking.

I did about 760 - 0mph brake tests in a row, one right after the other and the brake fade was almost non-existent compared to the stock setup.

So if you track your car I'd definitely suggest looking into this set up as cheaper alternative to brake kits and still gaining braking performance.

Even if you don't track your car...bigger brakes always look better.

You know you can resize your pictures, to make it load faster. :p Having high speed, it still takes 3 whole minute to load all the pics... We can't see **** until all the pictures finishes loading because is so damn big... not to mention the site wold shrink the pictures after it finishes loading anyway. No point of making them so damn big.

^^ I know the site shrinks them that's why I didn't bother to resize them. It was also 1AM when I posted so I wasn't really paying attention to why my laptop was lagging out.


They are resized now.

did the legend bracket line up or did you have to alter it?



The brackets bolt into the same place as stock Integra ones so there is no altering on that part.The shaving down of the inside of the bracket is so it can clear the thicker prelude rotor.

Quote: 94VTEC2ToNE on May/16/08 but what size rim do you need to fix those rotors/calipers underneath

I've seen them fit under fat fives, barely, but they fit. I didn't have to worry about fitment because I'm running 16's

The lines and bolts all went back in the same.


It's hard to name a price. I got a really good deal because a friend of mine is the manager at an auto parts store so I got them for 10% over their cost and he took my Integra calipers as core.


I spent less than $200 for everything.

Rotors, drill bit (to redrill them to 4x100), remanufactured calipers with clips, bolts, washers and pads.

I wouldn't expect to get that deal unless you know some people.

I wonder if anyone noticed his calipers are on the wrong side ,this is due to the Legend mounting them behind the wheel as opposed to in front of the wheel on the Teg,so you have to swap sides to make the bleeders upright.

Im really curious how you re-drilled the rotors, accurately. I guess you could lay the old rotor on top of it to mark the holes...How'd you do it?

I have a big rotor kit from AEM, and I definitely notice that they hardly fade at all. Bigger calipers would be nice though...someday.

Yes, thank you, I forgot to mention that.

on the Legend, the calipers are mounted on the firewall side of the hub, Integra calipers mount on the forward end of the hub so you need to install the calipers on the opposite side that they are meant for in order to get the bleeder valve on top, other wise you'll never get the air out.

Pretty much what I did. but instead of only marking the holes I C-clamped the old Integra rotors to the prelude ones and just used the old rotor's lug pattern as pilot holes.

A plus to using Honda Prelude rotors is that why are still the same hub size as the Integra so they are hub centric. That pretty much makes this idiot proof. If you can fit the rotor down the studs, it will center itself on the hub. If they're a little off it wont sit flush with the hub....in that case, just drill the holes a little bigger intill the rotor goes all the way down, it will center itself.

I could have had a machine shop drill them out for $20 but I decided to go to sears and buy the bit for $12. Not just to save money, but because I get to add a new tool to my collection and every car person knows, there is NOsuch thing as too many tools.

quick question for all the people that did this modification/upgrade.

After doing the Lude/Legend front brake upgrade, could you use the original front Rotors/carrier brackets on the rear? (i hate how small the rear brakes look through my wheels)

and what did you do about the Rotor Shield behind the rotor?
