hey everyone. my brake lines went out and so i had new lines put in. i also got a new master cylinder at the same time. i bentch bleed the mc and also bleed my brakes in the right order but i still have no pressure in my lines. i have to pump them three times before i can stop. anyone with any knowledge would be greatly appreciated

Well, its obvious that they're not fully bleed yet. Do it again until the pedal is fully firm. Do a gravity bleed and just let it drip to a drain pan of a small bottle.

yeah i have gone through three and a half bottles of fluid and still the same pressure as if i didn't even bleed them.

kommon_sense

doesn't take that fluid to flush the calipers/lines, so if its still a soft pedal, then you either have a botched mc install, or you didn't get all of the air out of the mc.

Since you changed the mc, did you use the correct mc for your car? Did you use the proper tool to adjust the pushrod clearance on the booster to match the new mc?

yes all the air is out of the mc. it is the correct mc for the car as well. i didn't adjust the pushrod clearance break booster but the last car i installed a master on didn't need to be adjusted. but do you think thats the problem? thanks for the reply
