(quoted from post at 10:09:11 03/12/22) I did not bench bleed the MC. Relied on bleeding after mounting on the firewall.
Why???????
Always bench bleed a master cylinder before installation.
Always.
Yes, adjustment at the wheels is essential too.
Gravity bleed the entire system in the proper sequence before attempting to bleed by using the brake pedal.
Also, in my experience, "pumping" the brake pedal is not the best way to bleed. I've found that having your helper simply push the pedal slowly down one stroke and hold it, then you open the bleeder until flow stops, close bleeder and have helper release the brake pedal then repeat the same procedure until no air is evident, repeat at each bleeder in the correct order.
In my opinion, pumping the pedal rapidly agitates the fluid and causes the air to mix into the fluid in smaller bubbles making it harder to get completely out of the system.
I've had excellent success bleeding systems that others have failed at by simply using the one stroke method.
STEP 1: Adjust brakes at all wheels ensuring brakes are centered as someone mentioned earlier.
STEP 2: Bench bleed MC before installation. ALWAYS!!
STEP 3: Bench bleed MC before installation. ALWAYS!
No, that isn't a misprint, it's important and can't be said enough.
Bench bleed MC before installation. ALWAYS!
Step 4:Bleed as described above.
