Hello everyone, I'm replacing both of these parts this weekend and haven't found a DIY on both being done together. Question is, should I flush the whole system and leave it dry before replacing both? Or will this affect something in a certain way... Thanks

you must bench bleed the MC, so make sure you have the right things to do that

i literally just replaced my clutch master 2 weeks ago. I did not bench bleed nothin'. I mean i tried but then all the fluid just fell out so i put it in dry. The FSM did not make mention of bench bleeding. Check out the youtube video which outlines the process.

Once all the parts are reinstalled, fill the CMC with dot3 or 4, open the bleed valve with a little tube attached, and wait till it drains without air bubbles. Because i left the fluid in the hard line- as i didn't need to replace my slave cyl- it drained thru in minutes- like less then 2 minutes so keep a real close eye that you don't reintroduce air into the system.

good luck

This is not true. I have installed many clutch master cylinders without bench bleeding.

I wouldn't be worried about introducing air into the system as it can be bled very easily and very quickly as Darcy mentioned. It's almost inevitable.

Old motorcycle trick, unbolt the slave and make sure the bleeder points at Jesus (perpendicular to the ground) gravity bleed it and you are guaranteed to get all the air out.

my mistake, i guess when i changed my cmc i didnt need to do it

Any recommendations on a particular brand of CMC?

There are two from BLOX racing, one that is to OEM spec and then a competition one. I'm eyeing the competition one with the assumption that it may be more durable for daily driving and it has a shorter pedal travel.

Neither. 100% Honda OEM is the way to go here. Majestic Honda is usually the cheapest.

Keep the fluid clean (turkey-baste) it moving forward for longevity after the install.

I'd like to add that I've had success with OEM replacements from Centric who is a reputable company. You can get one for less than 30$ shipped but there are some caveats from the manufacturing process... The hole for the lock pin might not be large enough for the OEM locking pin (pretty stupid).
OEM is definitely the most pain free way to go.
