Default Rear Disc Conversion??

So I've got an '02 Subaru SF-L with rear drums and the stopping power on there isn't amazing....I'm looking to do a swap to replace the drums with discs and calipers. I've heard it's not possible because the brake differential or whatever isn't able to be adjusted for discs and just cant be done. Is that true?? Help!

It is very possible. There are even a few conversions for sale around you right now. I think you'll be disappointed in the outcome of the conversion though. It will only really make a difference during prolonged aggressive driving; and even then if you have the right pads, good fluid, and the right touch. 4pots up front will give you more bang for you buck.

Forester L rear disc swap?

00 Drum to Disc conversion part list ??

Apparently the Google Search option still works This is the Subaru Forester Owners Forum! Stop on by and browse our huge repository of Forester information! - Search Results for disc conversion I know you're new, so this is what you can find using the Google Custom Search from the Search drop-down menu. I use this search feature all the time now.

Cheers
Doug

I had a Subaru shop near me do the rear disc swap(I also have an 02 L) and for the money and trouble they/I had to go through it wasn't really worth it. The initial bite of braking remains the same, although under hard braking I can tell the car slows down quicker. You'll run into frozen bolts, probably have to replace trailing arms/control arms/knuckle bolts. I went for a few weeks without an ebrake handle in my car because the guy who did it said the ebrake cables were too short, so make sure whoever you have do it knows all of the parts that you need to change out.

So in the end, not all the worth it? That's what I've also heard but i wasn't all too sure. Thanks for all the input! So i guess I'll probably scratch that off the list for now and focus on my suspension project!

Porterfield brakes. Cheaper, less hassle, and noticeable increase in stopping power.

Default not worth doing? BS!!

Ive done this on my previous forester, the 1998 NA SF5. There is NO PROBLEM fitting the disc setup at all!!! It took my local non-Subaru mechanic 3 hours to swap over!

02foresterL: Your local Subaru shop is either run my a moron, OR they ripped you off...

This is what I pulled out of a 1998 impreza (I ofcourse took off the struts and springs):



It fitted in with no problems, even with the wrx driveshafts, wrx brakelines, wrx hub, wrx parkbrake wires.

The only issue was such, that the ABS-sensorwire-to-harness coupling didnt match up, but the mech just cut the couplings off and soldered the wires together and its been working like that for 2 years now. Mind you, we ve got a lot of snow during the winter here in eastern europe, the ABS works a treat.

It def. brakes better with the rear disc brakes. My mate whom I sold this foz to fitted new rotors, greenstuff pads and braided brake lines. Now his foz brakes better than my current 99 turbo-s with (so far only) front 4 pot calipers fitted.

To get the ultimate in braking power with a rear brake conversion, you should get the master cylinder and proportioning valve from the donor car. This is especially true if your car has anti-lock brakes. The master cylinder and proportioning valve helps distribute the brake fluid correctly to all four disks with the correct bias. Disk/Drum setups use different components and have different biases.

is the proportioning valve part of the abs pump?
