you need
- 500ml of quality ( OEM HONDA ) brake fluid
- surynge with a bit of vacuum hose on the end
- long nose pliers
- Special Honda T peice ALB Bleed tool ( 95-97 Accord you can use a 10mm spanner, DC2 as well I think )
Steps: 1 locate your ABS or ALB system

it should look something like this, this is a Del Sol ABS Modulator
STEP 2: open the resivor cap and suck out all the brake fluid with the surynge.

when you have sucked out all the fluid, fill it up to the top with brake fluid.
STEP 3: locate the acumulator bleed nipple, blue circle, red arrow. it will have a cover ( green arrow ) remove the cover with your long nose pliers. do not loose the cover.

STEP 4: place the T peice tool on the nipple, ensure its cap is on properly, turn the handles anti-clockwise slowly until all the brake fluid stops rushing out of the accumulator. then close the nipple.

do not overtighten the bleed nipple.
STEP 5: locate your ABS fues box

lift the cover off, lift from the tab where the blue arrow is pointing.
STEP 6: locate and remove the ABS pump relay ( blue circle )

STEP 7: short out the two contacts that will drive the pump. on this type of set up its the two bottom contact that are closer to each other. IGN off.
DO NOT RUN THE PUMP FOR LONGER THAN 7 sec. this will prime the Accumulator with brake fluid from the resivor.

red circle, short out the lower two contact. ( blue line )
STEP 8: open the T peice tool lowly anti-clockwise to allow the pressurised brake fluid escape from the accumulator. Then close the nipple.

STEP 9: fill the resivor with brake fluid to compensate for the fluid you have just flushed out.
STEP 10: repeate steps 7, 8, 9 until you have flushed clean fluid out into the resivor of the T peice tool. do not allow its resivour to get to full. refit your ABS pump relay. refit the bleed nipple cover. Turn the IGN on to II. Allow the ABS Pump to run if the ABS computer doesnt sens enough pressure in the Accumulator, then recheck your ABS fluid level.

Notes:
you might think this DIY is useless coz you dont have the special tool, well you could be right, maybe you will apriciate the service you get at your Honda dealership. ( I wonder how many non honda workshops bleed your abs correctly ). or you could make your own tool. However CD5 and DC2 owners are in luck. on cars that are ALB you need the tool. on cars that are ABS with the square sided bleed nipple, you need the tool. On cars like CD5 and DC2 you have a hex bleed nippple, and the ABS modulator is in an accessible area, you can use a 10mm spanner and a brake bleed bottle instead of the tool. make sure you hold the hose down on the nipple as you open it as pressurised brake fluid is going to come out. open the nipple slowly and only a little bit. you can regulate the amount of fluid that comes out.
if your paranoid have the hose, sponge, suds and a bucket handy.
Type III ABS systems most post 96 cars will have the low pressure ABS system. these ABS systems do not have an Accumulator nor a ABS brake fluid resivor. They are blead as you bleed your brakes.
DO NOT SPILL BRAKE FLUID ON YOR PAINT WORK, IT WILL DAMAGE IT
have fun
