bleeding the brakes is a peice of cake, you shouldnt be getting air in the system if you do it right. like Win says dont let your master cylinder run out of fluid as it will create air pockets in the brake lines. what I do though is at step 8 just before I move to the next wheel I say UP to the person with the ripped jeans and make sure the nipple is closed, say Down , then OPen the nipple, wait till the fluid in the tube stops flowing then close the nipple, then say UP. do this 3 times. then on the last down get them to pump the pedal while you got the nipple closed and then get them to hold the pedal down, you only brifly open and close the nipple. do this to all four wheels and your sure not to get any air in the system. sorry Win for hijacking your nice thread.

When and how often do you do this? Thanks

[ECU-MAN]

every 20000kms or at least 12months also do your ABS if you got a pre 96 car, unless you got the special tool take it to Honda for the ABS. post 96 have the low pressure abs wich works off the master cylinder resivor so the ABS gets bleed with the brakes.

just a quick comment - what ECU-MAN wrote about the 8th step is VERY CORRECT!

when you pump the brake pedal while the bleeder is open, you are allowing air to slip back into the system.

Best Way to do it (like ECU-MAN said) is to have your friend Push the brake down and hold it down, you undo the bleeder valve, let the fluid and air out - MAKE SURE YOUR FRIEND IS STILL HOLDING THE PEDAL DOWN - LET IS SLIDE DOWN WHEN OPENING THE VALVE. then you close the valve and have your friend release the pedal. pump 1 or 2 times, press and hold the pedal, while you undo the valve and let the fluid flow while the pedal plunges to the floor - just repeat that!

8. Once you see the new fluid coming out of the pipe, tighten up the bleed nipple and ask your friend to stop pumping the brake. (I suggest you get him to stop pumping the pedal AFTER you have done up the bleed nipple to stop air entering via the bleed nipple)

so what are u saying??

did i say something wrong?

in the first post - point number 8 suggests stopping pumping the pedal after you close the bleeder so no air gets in...
I said you can't pump the pedal while the bleeder is open... ??? once you close the bleeder - pump all you want... no air will get in or out...

"ok, pump 1, 2, 3 HOLD!"

release bleed

pedal drops to floor

close bleed

"again, pump 1, 2, 3 HOLD!"

release bleed

pedal drops to floor

close bleed

"no more bubbles, gonna do the next wheel dad!"

"OK, let me know when to pump, the pedal getting harder"

"cool"

the KEY is the HOLD command

[tinkerbell]

yeah - step 5 need to be modified,

i suggest:

5. Ask your mate to jump into the driver seat and tell him to pump the pedal 3 or 4 times and then hold it to maintain pressure.

well if your bleeding... and your mate is pumping, who is pouring in the extra brake fluid? Do you need 3ppl then?

Also on average how many 500ml bottles would you need?
