Brake Swap, Solid to vented?

Featured Replies

Has anyone done the solid front rotor to vented rotor swap? i'm assuming that you need the caliper, pads and rotor, but do you need to swap the knuckle? and on a side note are the vented rotors the same for EA-81 and EA-82? BTW this is for a 1980 GL 1600

the EA82 stuff is bigger, not by a lot but they're bigger. I think anyways

you need the caliper, rotor, pads and the caliper mounting bracket since I believe its different. Everything else should work and it should bolt up to the car.

are there any other bigger brakes for older subes besides the 4WD discs? might need some for my larger tires and lift i want on ol' 86'.

Do i need different knuckles? This is for the front, not the rear, no bracket up front.

so all's i need are the rotor, caliper and pads?

Correct noah. Just the caliper, rotor and pads. Everything else (knuckle, hub) is the same. The EA82 & EA81 vented are completely different.

As much as i hate bringing a post back from the dead, and seeing them brought back, it occurs to me to ask another question.

 

Do the EA-82 front brakes work on the EA-81?

 

That is all.

I'm thinking about trying it if I can see an advantege to using EA-82 stuff

I guess i could too, i got both sitting in my driveway, i was just hoping that someone else had tried it.

 

Somewhat related note, has anyone tried the EA-82 master cylinder in the EA-81?

tried this on an 83 2wd hatch the other day, the ea82 calipers will not bolt to the ea81 hubs.. sux...

 

so you'd have to change the hubs, rotors, calipers and pads, to get ea82 brakes on an ea81

EA81's and EA82's have the same balljoints and the struts will bolt right in or with minor mods done to the strut. I'm not sure about the tie rod ends but you might be able to get away with using your old EA81 tie rod ends on the EA82 knuckles. Then its a matter of bolting on the calipers and the hubs/rotors.
