WTF are my brakes so shitty?!?!
 

My damn brakes suck...feels like I'm trying to stop a tractor trailer on a downhill, and takes almost as much space to do it too. WTF is going on here? It's a full 91si brake swap with powerslut rotors and EBC green pads, and the past 2 days they've been so shitty I warped the hell out of the front rotors. :P What the hell can I do to make this damn car stop faster, or better yet...what would be the best front rotor/caliper setup to slap on there for mad cheap? Been thinking about making custom caliper mount brackets and using a set of DA calipers on VW 11.5" rotors, similar to the fastbrakes setup.

Re: WTF are my brakes so shitty?!?!
 

if it's that bad i'd defiantely be looking at air introduced into the system at some point. do a big check of the fluid / air in the lines. Including the the master cyl & vacuum assist also.



on a personal note. kevlar pards (like EBC green & yellows) are the biggest ------- automotive joke of all time. they dust just as much, are no less expencive, require more of a warm-up to grip properly, even when warmed-up they have an inconsistant feel to them, and they have almost nothing for pad-life.
EBC FTL
Hawk HPS owns the piss out of EBC green's, they're consistant as ---- hot, or cold. they brake like a road pad cold, tip top end of street/strip pads on a track, and have a relatively ungodly long lifespan.



And next time. Skip the powersluts for some nice inexpencive brembo blanks. i really doubt you need the pad chewing slots. =) mad props for not being gay & buying drilled rotors tho.

Re: WTF are my brakes so shitty?!?!
 

u sure your back brakes are working good? mine were ---- so my front brakes would warp and suck and overheat alot. i swaped ex/si front brakes and gsr rear discs in now my ---- stops pretty hard. found out one of my front caliper slides were seized the other day too, that mad a differnce when i go that loose and greesed

Re: WTF are my brakes so shitty?!?!
 

Just use the e-brake and down shift when you want to stop.

Re: WTF are my brakes so shitty?!?!
 

Lol e-brake...kinda funny cause I almost had to do that today. :P The rear's are a DA disc setup, and they're working great so far but they also have stock pads on them. As for the powersluts, the only reason they're on there is because the crx parts car I bought came with them on it so I just re-used them. I'll try bleeding out the system again and possibly swap over a spare 7/8" master I have laying around and see what that does along with the Hawk pads. My local auto parts store carries them as their high-end pad, so I'll give them a shot with some new rotors. If that doesn't work, custom fab time. >:D

a 15/16th master cylinder does great for pedal feel also ;)

Re: WTF are my brakes so shitty?!?!
 

brake booster is most likely shot

*Cough https://www.homemadeturbo.com/forum/...?topic=80381.0 cough* :P

Re: WTF are my brakes so shitty?!?!
 

check the hose & check valve first!

Re: WTF are my brakes so shitty?!?!
 

Explain? The one I have on there now if a 15/16th's...pedal feel blows :P It feels ok at first then it starts getting spungy as the front end of the car starts shakin' cause the rotors are warped so bad :-XHmm...never thought of that one...time to dig out the spare, sounds like I've got a mission tomorrow.

Re: WTF are my brakes so shitty?!?!
 

prop valve? master cylinder
my guesses ???

Re: WTF are my brakes so shitty?!?!
 

yeah, is the proper proportioning valve in the car? I'm not too sure on which you'll need for you setup. If the front brakes are different from a DA, and you have a DA prop that could cause problems.

Re: WTF are my brakes so shitty?!?!
 

The prop valve is from an Si...40/40 and it should be the same as the DA anyway. I'm gonna try replacing the master and rotors today and see what that does.

Re: WTF are my brakes so shitty?!?!
 

:y

Love the HPS pads.

I am running the stock Si rears, a setup like the 11" Fastbrakes kit on the front, and a 15/16" master cylinder. It will overpower the street tires pretty easily.

Re: WTF are my brakes so shitty?!?!
 

i dont believe this... my 88 CRX HF had 90-91 EX brakes up front, disc's in the rear and a 15/16th with no brake issues at all... i never put a 4040 in my car...
i have a 93 Civic CX now with DC integra brakes on all corners, 15/16th...NO 4040 (or change) and same thing just great brakes!

hell i recently found a 4040 i got for the CRX, and sold it... i dont believe the hype...


i have a set of Legend brake calipers forsale ;) bigger brake = better stopping...

Re: WTF are my brakes so shitty?!?!
 

Well, I just put on the rotors (lucked out...auto parts store did have brembo blanks...someone ordered them and never picked them up ;D ) and changed the master to the 7/8th's unit...pedal is hard as a rock now. The master must of been pretty well shot, they feel pretty good but still take a while to stop...probably because they're still the stock 9" rotor size :P I'm gonna check out some corrado g60 rotors and some other ones, whichever gives me the 11" rotor and still has the same 4-lug spacing. Then just have to make custom mount brackets for the caliper bracket lol. Here we go again. ::)

Re: WTF are my brakes so shitty?!?!
 

good for you :)
just always remember. EBC (kevlar) pads are bullshit, and slotted rotors chew pads like crazy. ;)
oh, and when the pedal drops ot the floor it's not the pads. you boiled your fluid out. ;) upgrade it! it's when you push your pedal and it's still hard & has resistance, but you don't stop. THAT is when the pad's have melted, and a higher quality pad, and/or slotted rotors should be used.

Re: WTF are my brakes so shitty?!?!
 

Actually the slotted rotors didn't do too bad. Even with oem type pads they lasted a long time. After the EBC's they def. had a shorter stopping distance, but after a while they just started to get worse and worse. Another thing I noticed as well...the blanks are thicker than the powersluts I had. Maybe these will take the heat a little better and not warp as fast, but I can almost garrentee they will warp eventually with the way I drive. :P Of course, I highly doubt these dookie 17" wheels are helping me any either...I really need to get a set of 15's badddd. Anybody got some spare 15" rims laying around? ;D

Re: WTF are my brakes so shitty?!?!
 

I ran through my first set of EBC green pads on slotted Brembo's on the lexus in 2000 miles in the front, and 8000 miles in the rear. that wasn't racing lmao! the next set only lasted 4-6k i don't remember
i have over 20K on my hawk HPS's. they're still abit over 50% life. and when i do drive the lex, it's just as aggressive as ever hah

those pads are total pieces of ----. and beyond anything else their braking isn't particularly good. ewwy



just keep in mind brembo suggest 1000 miles for a break in hehehe

Re: WTF are my brakes so shitty?!?!
 

1000 miles?!? :o Holy shitsky...that'll take me a week and a half to do lol. I figured I'd go out on the highway around 2am and do around 10 60-10mph hard brake runs, let her cool for a while, then do another 10 and cool off.
