Default benifit of rear disc?

ok so i have a 1992 hatch with factory brakes all around.i just put new rotors and ceramic pads on the front. the rear drums are shot and need to be replaced aswell.i am planning on getting the rear disc swap from a 94 integra. i know that the rotor caliper set up is heaver but im not doing any drag racing so the extra couple pounds doesnt bother me really.one problem i do have with my honda is it seems when your doing some heavy driving. makeing many stops from high speeds one after another the brakes heat up alot.basially just looking for some input on the the (DC) 94+ integra disc on my 92+ civic hatch (EG) thanks

What front brakes will you be running? Lots of guys use the Integra stuff all around on EGs, works very well.

The reason I use them are really just for maintenance. I HATE working on drums. Plenty of roadrace guys use rear drums, and that weight benefit is even more prominent in roadracing than in drag racing.

Drums or discs, anything will heat up too much if you aren't running the right pads/shoes.

other than the cosmetic factor of having rear discs, the ability to easily service a disc is a strong selling point (once you tried working on drums). i doubt you'll feel any difference in braking power by adding rear discs however...

I couldn't say it any better. I switched mine over for ease of service. However when I build a race car I will run drums for the weight advantage.

yup. i went disc cause i needed both side wheel bearings and figured it'd be a nice upgrade. then when i built the b-series car i figured i had to have rear disc being that the car was faster. but now i wish i had left the drums on just to compare brake feel and pad/shoe life. plus it would look awsome. 11" front, drums rear.

I was asking myself if this was a logical step for braking performance. But it seems, weight savings work better. I all pro weightloss. :D

i always thought that drums might not be as consistant because they may hold in the heat and get hot faster than the discs up front?? dunno, thats why i did mine and looks, i wont even lie.

well i have a 96CX which uses the same prop valve as a 99SI and now i have integra brakes all around so i just kept my stock one since its the same, but 92-95 civic owners should change them...

Yeah, EG Civics use the 4040 proportioning valve. Not sure about the EF guys. For the heat retention thing, it does make sense to think the discs would cool off better. This might be the case, I'm not sure. However, again there are lots of H4, H5 and IT racers out there using the rear drums for wheel-to-wheel competition. Somehow it's working fine for them

Shoe choice, man, I don't even know what's available. I like Axxis Ultimate pads in the rear, not sure if they make a shoe in that compound.

I used stock ones as anything aggressive cause rear brake lock up in my experience.

The only thing I dislike about running drums is having to adjust them

i ran all last season, 15 race days with the stock Dx drums. I needed new bearings so i did like Lo-buck and converted to rear disc for this season. i also upgraded to b series and goin H2 instead of H5. I never adjusted the rear drums and did just fine. You dont use brakes in a h5 car anywyas

Care to enlighten us? I KNOW the aluminum drums are lighter than discs.

prop valve-you do have to change it on the ef. sure, youll se people on the street with all kinds of bo-hack stuff. but there not braking nearly as hard. and yes, for grins i tried using the drum prop valve on my 11"f/rear disc on my racecar. it sucked.
what drum brake shoes do yall use for roadracing cuz i would like something equivalent or close to my ebc reds that are in the front of my eg

shoes-people are using oem or oe replacement shoes. carbotech does make shoes but, like i've been saying for evAr, its too much rear brake. you end up getting all kinda of rear lock up. we actually tried them on Z's h5 car and ended up spraying wd-40 in the drums to glaze the shoes over (thus taking out some rear brake) <U>just because your running aggressive front pads and stock rear pads/shoes does not mean your braking system is now unbalanced!</U>

a few of the the drag race guys have compared weights and found them to be about the same, some found that the disc setups were lighter. But this is also comparing the entire traiing arm/brake combo to one another. Maybe some of the trailing arms are different.

You'd also have to take into consideration WHICH disc setup you're talking about. The Civic rear disc (Si? EX?) has a smaller rotor, maybe a smaller caliper than the Integra one. The ITR one has a bigger rotor still.

i thought ALL the rear disc for civic/integra used the same rotor/caliper accpet itr from 88-00
and yes, some trailing arms are differant. the da/ef the offset of the arm is differant (always wondered why my +38 wheels fit alittle odd in the back)

I noticed that when autocrossing, my rear disc brakes don't lock up as soon as my old drum brakes did. The look and ease of maintenance was a big selling point for me as well.

Correct. Rear disc setup for 88-00 civic and 94-01integra is the same. The itr was the only one with a different rear setup.

When I converted to rear discs, I noticed that the car seemed to be a little more balanced during braking. However I was still on stock suspension at the time. It might not be as noticeable on a car with a stiffer suspension.

rear drums for H5/ITB using stock shoes.

adjusting them once per season just because i feel like i ought to be doing something on them.

don't waste your time/money.

all of the serious people i know that went down that disc path regretted it.
