So for all those interested here is a break down of all the cost associated to do a rear drum to disk conversion on a 1999 Honda Civic EX:

Parts/Cost List: (Not all the parts from the Acura will be used)
2 Rear Trailing Arms (left and right out of a 98 Integra) with calipers, rotors, brake pads, compensator arms, upper arms, and lower arms
Total $257.00 after tax and other BS charges + 1 hour of labor

2 replacement trailing arm bushings - $49.33 shipped
1 Bushing extractor tool - $122.20 shipped (ouch...)

(This is optional - I could have gone with stock rear lines off a Civic Si for cheaper)
99 Civic Si Russel Stainless Steel Braded Brake line kit front and rear - $94 shipped

2 Emergency brake cables for a 00 Civic Si - Total $119.44 from Honda

I decided, based on what I read, to not replace the proportioning valve. If the rear brakes give me any drama I will have to do this.

Honda Brake Fluid + Silicone Lube $20
4 Cans of brake cleaner $4

Total Cost: $665.97
I can sell the bushing extractor after I'm done with it so $555 is closer to the real cost.

The plan is to install this over spring break (March 14) hopefully everything will go smoothly. If not I'll add additional costs I run into.

 

wow it cost me $100 to do my rear disk on my EG

 

You got the rear brake assembly for $100, or you got all the crap I listed for $100? I'd find that hard to believe. Rotors and Pads alone will cost $50-100 depending on what you get, that leaves $0-50 for the trailing arms and calipers.

Rear trailing arms + calipers for $100 I can see. I thought what I paid was a little high... But for everything else unless you have some inside source...

Another thing I got screwed on, I needed most of my parts from an EM1. EG models are a lot more common and older. I saw six 92-95 CIvics in the yard I was at, 2 of which were 92-95 Si models. I didn't see any EM1 trims. I didn't know if the parts would swap over from the older Civic Si models. I went with what I knew would work.

What all did you pay the $100 for?

 

where did you get the parts for that conversion???? 100bucks???damn hook us up man......

 

i got the trailing arms assembly, e-brake cables, calipers, rotors, new pads, ect i did everything you did but the replacement of the bushings. i got it off a local forum...i guess its $130 after i bought the cleaner and fluid
