Default Bleeding Multiple Times

Did anyone have to bleed their brakes multiple times after switching brake lines and calipers?

I bled mine once and the pedal is like a marshmallow. I bled them until all the bubbles stopped.

What a biatch to have to do it again!

Small bubbles like to trap themselves, after a few days the small bubbles will merge into bigger bubbles and will be easier to bleed out. After a line/caliper swap i like to bleen the brakes a couple time in the following week.

if it's still mushy after bleeding, hit the caliper with a mallet a couple of times. you could also try tilting the caliper up so it's about 90 deg (making sure the piston can still contact the rotor).

You need to get a pressure/power bleeder. I bled mine sseveral time the old method and still had a soft pedal. After getting the power bleeder, it forced out more air even after the earlier, multiple bleedings. Pedal is hard as a rock now.

when you were bleeding your bbk, sometimes helps to remove the caliper bolt, and hold the caliper upright so the bleed valve is directly up.

+1 on the power bleeder/vacuum assisted brake bleeder.

+1 to all of the above. This only applies to new calipers though. Pockets of air will get trapped internally in the calipers. Small light taps with a rubber mallet will dislodge the air pockets/bubbles....

I had my calipers powder coated so there was no fluid in the calipers at all. I did hit them with a rubber mallet when bleeding. I also used a Motive power bleeder pressurized between 25 and 30 psi. I guess maybe since I was starting with 4 new calipers and lines it's the worst case scenario for bleeding.

I will bleed it again today but I don't want to do it again!

i used a set of speed bleeders on my dad's Z06, works like a charm, no air bubbles and you can do it by yourself!
