[civicVI]

i just did the rear disc conversion on my civic eg hb

just have E brake
i jump into the driver seat and press the brake pedal down and then release it up.need to did that few times then can feel the brake.

u need to bleed from the back 1st then do the fronts last

[ksl]

when you press the brake pedals, is it soft, or just like normal when to apply other brake?

but high chance there is still air in it.

[civicVI]

its soft
i bleed them more then 2 hours still same
when start engine the brake will be soft
when off engine the brake will be a little bit hard

got prop valve?

[90LAN]

check for leaks

got prop valve?

yes put them in

[civicVI]

check for leaks

checked
no leak
just test drive .. the brake so soft need to press the brake pedal down(at the bottom)then it can stop.

is it wrong step??
i need to bleed from the back frist (a pair) then front(a pair)?
because i bleed them one side then the other side

[civicVI]

i was wondering may be the brake master cylinder not big enough but i just up grade the rear so should be ok since i did some research from ozhonda

correct. not side to side, but both rears, then both fronts

make sure you bleed them properly

do u think the brake master cylinder not big enough?but i dont think so even some people change to EK4 whole brake setup still havent change the brake master cylinder

Best to have 2 people to help you bleed.

to get rid of all the air you must step on the pedal, tell your buddy to hold the pedal down then u open nipple for about 2sec then close the nipple then your friend can release pedal. Repeat this as many a 40 times on each end. like lan said do rear first then front last and always start with the corner furthest from brake booster/mc.

Check your brake fluid levels...

when i bleed them
do i need to turn on the engine or off the engine?

[shadou]

err engine off, bleed FURTHERMOST from the Master cylinder. Get a mate, you'll need to do this at the last stage as it's most important, nipple tightened, pump till hard and open the nipple (DO NOT RELEASE THE BRAKE PEDAL) tighten up and then redo till you see no visible signs of air bubbles. One other factor is that may be during this installation and the bleeding process you've damaged seals on you current master ?

[V73C]

lol you must be doing this by yourself or something ? pumping it then letting go of the pedal to go out and bleed the valve yeah ?

[civicVI]

i did that with my mate :)
brake still soft but better then b4
wait till week end do it again
