I want to replace the front brakes on my 02 civic. My question is, do I have to replace the rear brakes at the same time?

 

Not necessarily.

If everything is working properly with the car and the driver (not leaving e-brake on, etc.) the rear pads can usually go about twice as long as the front, if not longer.

I'd always check the rears though when you do the fronts, just incase you have sticking calipers or the e-brake isn't fully releasing.

It doubt you'll have those issues since your car isn't that old but better safe than sorry, especially as I've let people drive cars of mine in the past who left the e-brake engaged until they could smell the pads

 

I'm looking for information on how to convert my drums on my 94 dx to disc (ie if its possible an where to get the brakes)

 

nope ... if the rears are in good shape dont worry about replacing them, fronts tend to wear faster as they handle a heavier brake load

its possible, best option is to find a complete rear brake setup from a 94-01 teg, you will need everything from trailing arms to e-brake cables. do a quick search on the subject and you will find numerous threads about the conversion

 

thx

 

a 99-00 si rear disc brake conversion is good too.. everything is a bolt in process except for maybe the ebrake cable.. other than that u will need the SI M/C, proportioning valve, and the soft lines for the brake lines..

 

If i were you i would just replace the back also. Your already replacing the front ones...why not the back too. Saves you from doing it later on.

 

master cylinder is not necessary (more for pedal feel than actual stopping power), but the prop valve is definitely recommended.
