I thought I would post this up here instead of burying it in my build thread. Does any one have ideas on how to bench test a brake booster? I have an assortment of 5 or so small boosters. I would like to bench test them to see if any of them are good. Then restore the best candidate Thoughts?
Could someone please post a pic of their 240z brake check valve? I can’t locate mine maybe it doesn’t exist My running, almost rust free 1973 240z scraed me a bit on my first drive yesterday. The brakes are horrible. Feels like when I botched a bleeding on my wife’s brakes years back. Lots of pedal effort with just gradual slowing. Applying brake while idling causes an increase in RPM. A squishing airish sound when the brakes are first applied. I was originally thinking it was definitely the booster. Then I started to wonder about the check valve. I can’t even find the check valve. I assume it’s on the vacuum line somewhere between the brake booster and the engine. Assistance would be greatly appreciated.
As part of replacing the failed brake booster on my 72, I chose to suction most of the fluid from, and remove the master cylinder from my brake lines. Didn't want to risk bending brake tubing. After the new booster is in place, is it necessary to bench bleed the master, or can I just install it and bleed the lines as normal? I'm only asking because if I should bench bleed, I need to secure some plugs to block the line connections. Thanks
So, my "new" 73 has a new master cylinder and the other day I found it a bit hard to stop. Peddle is rock hard. Pulled the vacuum line imagine bay side.n it let out a Lil wet vacuum noise. Cabin side I can hear a squishing release sound. The kicker is, i'm not losing fluid into master. In fact it's,very full. Any ideas?
