need rotors and calipers

hellview · Jan 29, 2009, 03:41 AM

ok wow i havent been on here in forever.

ok i was at ntb today because i need my flat fixed..turned out nothing was wrong with it.
but

they said i need new rotors and calipers. the outside brake pad was almost bald and the inside one was almost new. and on the backside of the rotor was all rusted out to ****.

so. i was looking at the rotora brake kit from rrm but thats way outa my price range.
so im think im gana get the "street series slotted rotors" from them.

my main question is, what are my options as to calipers. i want nice ones but im not talking brembo or anything. just some good inexpensive ones.

189$ for the rotors.

ntb gave me an estimate for everything (rotors, calipers, bleed/flush brk line, labor,ect) and it came out to 782.32$
..
i dont want to pay that much
..
i plan on installing my self.... well, with 90% help from friend.

so..

what are my options on calipers?
alternative for rrm's rotors?

ps: man i wish the rotora kit wasn't so expensive. they're gorgeous

So wait your calipers are bad? They make rebuld kits I think, or so I rebuilt a dsm set once. Otter knows what type of dsm calipers fit, i think he tried that route.

Also don't always believe what local shops say, bring it to another shop for a 2nd opinion. Yes your pads might be worn, but they might be pulling your string regarding the calipers.

I doubt galipers are seized on a 2004 car unless you let it stand for 10months with the hand brake on.

For rotors if you read a bit on the web you will find that slotted rotors and cross drilled aren't that much better than replacements one you'll find at your local parts store...not for daily driving and occasionnal lapping that is. Better spend your money on good pads and buy rotors more often if you eat through them.

For the Galipers it is the 2nd Gen DSM galipers that fit but you need a custom brake line as both end fittings will be different or some type of custom fitting so you can plug your oem lines on the galipers.
2nd Gen DSM galipers do not have bigger pistons or strenght, the specs are the same as the ones on our ralliart but they have a 2 sliding piston setup while we have only one. Meaning we have 1 big piston, they have 2 small.
Having 2 small pistons will make the pressure on the pad more equal on the surface of the pad and might give you slightly better braking.

IF you plan on doing this, best thing you can do is change you brake fluid for better one, this will avoid getting your brake pedal sluggish after a few runs at your local racetrack

Read quickly through my old thread from when I re-did my brakes (including calipers): http://forums.evolutionm.net/lancer-...questions.html

Did they say why you needed new calipers? Unless your pistons seals broke and the calipers aren't retracting, you shouldn't need new calipers. If that is the case however, you can rebuild yourself for about $15 or so. I can make a thorough thread on how to do that, as well as doing all the labor you'll need to do (I've been wanting to get around to that anyways). Aside from DSM calipers, the only calipers that fit stock brakes you can find out there are just rebuilt calipers from a company that recycles calipers and re-builds them all nicely. No reason to go that route, cuz you can do that yourself, and they're pricey.

You have a few options for rotors. RRM has some like you saw, R1 concepts also makes some awesome rotors, their premium series is top notch, I'm very impressed. Plenty of other brands out there, I would consider those two first.

Pads: everyone has recommendations, depends on what you use your car for.

il ask about rebuilding them.
becasue the outside pad was worn down and t he inside wasnt, they said it was the cylinders or something thats causing it. and they said i need new ones.

ya i know i still dont 100% trust mechanic shops .. but its not like its a "local shop" its a NTB. its a big company. they just opened like not even a month ago to.

but il ask around about rebuilding them.

can u give me some links for rotors.
and what makes drilled slotted or just slotted better than regualr rotors. stoping performance? thats wat ive always thought.

and im not racing or anything, it is my daily driver ..but i want it to be good performance. . thats why we bought the RA's isnt it lol.

1 being daily driver and 10 being race car. ra=5 lol, a little exaggerated but watevs ha

Well being that its NTB you still never know... just get a second opinion just in case cause they might just give you an extra problem so they can fix it and get your money.

Regarding the rotors if you're not tracking the car, drilled/slotted wouldn't really make a difference over stock rotors but they're more for looks I guess unless you hard break like crazy and heat your rotors. But slotted is better then drilled due to the drilled holes chance of cracking under the heat. Dimpled is a nice in between.

It would´nt make a noticeable difference (between stock and slotted, dimpled or drilled) in stopping power, just longevity because vented rotors will work as to guide air through the disc to cool it. The big difference (when dealing with extreme heat and multiple cycles) can be felt with the internal vein design (radial like stock, centrifugal like some high end 2 piece rotors, paw designed like some brand rotors,etc.)since each design may or may not have good airflow properties and even then, the difference will be brake fade or lack of it.

As for stopping power (thinking of stoping distance no matter how many cycles), the only important thing about discs is the effective radius. Since Torque = Force x Distance, the greater the distance, the greater the torque. Here´s a little diagram I made to show what i´m talking about.

Note that when it says radius, it refers to the disc radius where the pads meets the rotor. Some pads have different shapes that may or may not enter in contact with the full face of the rotor.

The advantage to upgrading the caliper is that you go from a single piston to a twin piston which means the pad is going to grab firmer and more evenly on the disc not that you would really notice on the street but it would be noticeable on the track.
If you track the car then you would be wanting a slotted disc only as the drilled and slotted disc have a tendancey to crack as there is just too many cuts and holes in them - down this way the track officials actually recommend that you swap over to a better disc as they have seen too many failures becasue of this.
Not sure if you have this car over in the US but the FTO, evo 1,2 and 3, there are also some magnas or what I think your verssion is called a Galant, VR4's... basicly anything that is early 1990's to late 1990's these calipers are a perfect match for our cars
