hatchsub Posted September 25, 2009 Share Posted September 25, 2009 Do i remember right that it was 84? I got an 83 so its got solid rotors that are warped to hell. Going to ebay and getting a set of vented along with new calipers from rock auto. Link to comment Share on other sites More sharing options...
Turbone Posted September 25, 2009 Share Posted September 25, 2009 I think it was 83 and it had to be a AT to have vented rotors. Link to comment Share on other sites More sharing options...
bheinen74 Posted September 25, 2009 Share Posted September 25, 2009 and the 85, 86, 87 all had them...no matter what transmission it has. Link to comment Share on other sites More sharing options...
monstaru Posted September 25, 2009 Share Posted September 25, 2009 i am remembering a difference in the non-vented vs. vented rotors.i am thinking the non-vented are a tad thicker,which in turn means there will be play if you put a vented rotor in. i this happen to me on one of the brats.cheers, brian Link to comment Share on other sites More sharing options...
hatchsub Posted September 25, 2009 Author Share Posted September 25, 2009 I think it was 83 and it had to be a AT to have vented rotors. That would mean mine should have vented rotors since its an 83 and used to be an Auto. Now im confused lol Link to comment Share on other sites More sharing options...

kiwi subbie Posted September 25, 2009 Share Posted September 25, 2009 Dads old 1984 1600cc 5spd sedan had vented rotors Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted September 25, 2009 Share Posted September 25, 2009 To be safe, you can probably get all the parts you need from napa, just order them for a 1986 Brat. I think you need calipers & rotors to make it work right, backing plate should fit still... And you come out with all brand new stuff. Turn in your old crap as cores, they wont know the diff.

zyewdall Posted September 25, 2009 Share Posted September 25, 2009 Sometime in '82 I thought.... because I had trouble getting the right parts for my '82 GL wagon, and they claimed that it was because they switched rotors in the middle of the year (or they were just making excuses).

NV Zeno Posted September 25, 2009 Share Posted September 25, 2009 My bone stock '83 GL 4WD 4-speed manual has vented discs... Just my 2 bucks Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 26, 2009 Share Posted September 26, 2009 It was a mid-year change in '83. My '83 hatch has them as well (4 speed D/R). They did a mid year update in '83 and changed several things like the vented disc's and the clutch cable's, etc. GD Link to comment Share on other sites More sharing options...
NV Zeno Posted September 26, 2009 Share Posted September 26, 2009 Yep, mine has a build date of 6/1983. Link to comment Share on other sites More sharing options...
Mykeys Toy Posted September 26, 2009 Share Posted September 26, 2009 I dont have a build date but, My 83 Brat has vented.. I ordered new rotors once and got non vented and the brakes didn't work right.. It took me over a month to figure it out, and it was my daily driver.

TomRhere Posted September 27, 2009 Share Posted September 27, 2009 No,, it don't work so well to mix solid-vented brake parts. Whoever the former owner of my '86 BRAT was, (before 86subaru bought it), swapped in an older solid-lifter motor. No problem there. But,,,,, they also swapped a solid rotor onto the PS keeping the vented caliper in place.. Worked ok, until the brake pads wore down. Then it decided to chuck the outer pad out of the bracket when I hit the brakes. Luckily, I was just a few hundred yards from the driveway when that happened. 4 year old Grandson and I made home with no issues. I promtly put the correct parts back on....

Gloyale Posted September 27, 2009 Share Posted September 27, 2009 Worked ok, until the brake pads wore down. Then it decided to chuck the outer pad out of the bracket when I hit the brakes. Yeah, that is a flaw in the Design of the vented caliper and pads. I had the same thing happen on 2 different 84 EA81s, both still with original vented rotors.. The bracket is just a bad design, it allows the pad to slip out when it gets to thin and worn. MAking sure you have ALL the little sheet metal clips and spacers in the brackets helps alot. They are cheap.....it is just getting the counter guy at the dealership to look at the old parts books..... Link to comment Share on other sites More sharing options...

Not sure i understand this. I was never intending on mixing and matching parts. I was going to get vented disk brake calipers as well as vented rotors so that i have the whole vented package. I just needed the years that i could ask for to get the correct parts. Link to comment Share on other sites More sharing options...

TomRhere Posted September 28, 2009 Share Posted September 28, 2009 http://www.rockauto.com/catalog/x,carcode,1267725,parttype,1704 Those 1st 2 are what I bought for mine, doesn't matter that they say for A/T, they fit. Vented rotors are $22.XX or $12.XX on close-out. My previous post wasn't directed at you. I was merely commenting on the mix-n-match that was brought up. It don't work to well....

hatchsub Posted October 4, 2009 Author Share Posted October 4, 2009 I just now stumbled on those today. Anyone else have any experience with them...because my wallet is guiding me towards the 12 dollar rotors and the 47 dollar calipers. Should i be wary of them or are they good stuff?

GeneralDisorder Posted October 5, 2009 Share Posted October 5, 2009 Should be fine - this is an EA81 after all - and a 2WD one at that. Light car, 75 HP..... not exactly a performance machine. Any of the availible offerings should do you just fine unless you drag on the brakes all the time or drive like grandma - if you compression brake like you should, rarely use them on the freeway/highway like you should - they will outlast the car.

hatchsub Posted October 5, 2009 Author Share Posted October 5, 2009 75 HP..... not exactly a performance machine. GD Not yet...... Still working on that one lol...or at least making it zippier. Thanks for the advice. Im ordering them tomorrow. Im tired of these warped rotors. Link to comment Share on other sites More sharing options...
