Assuming you have the correct year of WRX caliper to match up with your year of RS then all parts are interchangable.

Usually, I'd be able to tell what ear RS you had because you'd have typed something useful in the vehicle field. Then I could give better advice, but you didn't so I can't.

If you change calipers you absolutely MUST bleed the brake system. It's less an issue with the lines than the calipers. The new calipers will be empty of fluid and you need them full of fluid and the only way to do that is to bleed them.

Even if your calipers are interchangable, I don't see a real need to swap the calipers. When was the last time you heard of an old car having a problem because of the brake caliper.

An 02+ RS calipers/pads are interchangable with an 03+ WRX
before 02 RS is interchangable with 02 WRX calipers/pads. Sometime in the late 98/early 99 RS the caliper changed also, but I'm much less sure on those specifics.

If the pads are interchangable, I'd try both and see if there are any differences. Use the set you feel performs best. Compatibility of the WRX rotors with your pads should be a non-issue as long as you do some bedding in.

Goose,

The caliper is exactly the same.

If you decide to keep your stock one, you don't have to bleed the brakes.

All you NEED to change is the rotor and caliper braquet.... simple 10 minutes job per side.

Talking RS--> WRX front brake conversion...small questions...

Hey all! I'm doing a WRX--> RS front brake conversion soon...mostly out of neccessity...my front brakes are shot!

Anyway...I bought a used front brake assembly from a fellow member...it includes the rotors, calipers and caliper brackets and pads...all used around 10,000 miles. Should be in good condition, right?

Now, I found the instructions on scoobymods.com..it seems pretty straight forward.

But, since I'm getting WRX calipers, should I replace my RS calipers with the newer WRX ones? Or just keep my old calipers? Is there any advantage to the WRX ones?

Also, I changed my brake pads at around 48,000km (I think thats like 30,000mi)..my car now has 73,000km (maybe around 42,000miles)...can I keep my old pads? Should I use the WRX ones? I guess those pads will already be seated with the rotors I'm getting..since they are from the same car.

And, lastly, are the pads interchangeable from caliper to caliper? Can I use the WRX pads in my RS calipers, and vice versa?

Oh...and will I have to bleed the brakes if I change calipers? I assume that I'd have to remove the brake line frm my old RS caliper to install the WRX caliper...and the brake line would piss out fluid in the process...but would that neccassarily mean I have to bleed them, or just top off the fluid?

Thanks gang!

Gooseman,

I did this mod for my RS also....... I too have 02 WRX brakes... but I kept the WRX caliper in my spare parts bin (cause it's the same caliper)...

The pads are also identical in size for the 99+ RS and the 02 WRX...

Just change the caliper braket, pads and rotors.... onto your car and keep your old stuff as spare.. unless they're done...

I kept my RS brakes since I'll switch back for the winter cause the stock front WRX brakes don't clear my 15" steelies with winter tires....

and don't overtorque the brake components... I think torque is 40-44 on the caliper braket and around 30 on the sliders..... I'll double check....

Very easy job.... and it looks good too.....

Robin
