Well it doesn't seem to be a problem with the brake booster at all. I think it can be, either bad quality brake washers, or worn out master/wheel cylinder(s). Or may be both. Do not waste your money on replacing the brake booster. Check the master pump bore and washers. If the brake fluid level does not dorp, I'm pretty sure that the problem lies in the master pump itself.

Hello, I'm a new member for this site & I just finished registration. I also love this topic so much. Currently I'm rebuilding a Mitsubishi TD-04 & a Toyota CT-26. I'm planning to start turbocharging my stock G11B engine(Lancer Box), just after finishing rebuild job. I'll let you know if it goes well. Thnx.
