Hi, I got a brake booster & MC of the DC5 with 15/16" to upgrade for the stock ek1.
However, the bb&mc from the dc5 have abs unit while my ek1 doesn't had ABS.
so just wondering can i replace it? or i need to get the non-abs larger bb&mc to upgrade.
thanks
Update in evening
First, thanks 90Lan to confirm that i can use the ABS DC5R bb&mc in EK1 :P
Since both of the Ek1 7/8 and DC5R 15/16 brake booster and master cylinder are sitting in the room, i just take few pics and measure the dimensions to show everyone the similarity and differences of them.
The left is DC5R while right is EK1
Pic 1 - show the size of mc of them.
DC5R = 15/16, EK1 = 7/8
Pic 2 - show the overall diameter of DC5R is smaller than EK1
Pic 3 - however, this pic shows the DC5R had thicker booster compare to EK1.
Pic 4 - shows the shaft of the DC5R is bigger than EK1
DC5R = 56.5 mm, EK1 = 50.9mm
Pic 5 - but, this pic shows they had same length of the screw to connect to pedal.
Pic 6 & 7 - shows they had the same length between the top and side screw
So, conclusion is - you can upgrade ur civic with DC5R brake booster & master cylinder. this wil increase ur brake significantly.
"BUT" there is always a but. which is the civic had one hard line on side mount while dc5r had it on front mount. SO, you had to modify ur hardline to get them fits.
I wil do this conversion in coming few days. hopefully it wouldn't be too hard to modify the hardline.
