Phantom Posted May 20, 2004 Share Posted May 20, 2004 Ok - I'm confused. I have essentially stock brakes on my 280Z. Disks in front and drums in the rear. To keep the rear drums properly adjusted one of the ways is to brake when the car is moving backward. I did that at a decent speed today and got a surprise. When I hit the brakes going in reverse they were firm and braked well. I stopped, shifted to 1st, drove forward, and braked again. This time the brake pedal was soft and required more travel to brake. Any ideas?? Quote Link to comment Share on other sites More sharing options...
DaleMX Posted May 20, 2004 Share Posted May 20, 2004 I'm having a similar problem. I have replaced the MC, the calipers, and the wheel cylinders. I bench bleed the MC, and bleed the snot out of the brakes. Even blew out the lines as Tim suggested and the pedal is really soft still. I am suspicous of the factory valve and have ordered the prop valve kit with front bypass from Ross. If that does not fix it then I will assume that the new MC is at fault. The only other thing left would be the booster. I'll let you know how it all turns out. Dale Quote Link to comment Share on other sites More sharing options...
Drax240z Posted May 20, 2004 Share Posted May 20, 2004 Phantom, don't trust the self adjusters in the rear brakes, adjust it manually and get it close. My self adjusters weren't working at all, and they really don't work that well unless they are brand-spankin-new. Try adjusting them manually first and go from there.

Tim240z Posted May 20, 2004 Share Posted May 20, 2004 Yeah what he said!! If it works well in reverse, but sucky in forward, it is definitely the adjusters. Quote Link to comment Share on other sites More sharing options...
Phantom Posted May 21, 2004 Author Share Posted May 21, 2004 It's amazing. I open up the Factory Service Manual and it actually tells me that I can adjust my rear drum brakes by cycling the hand brake several times. I pumped it up and down about 8-10 times and I'll be darned - they worked better. Drove it a ways, did it again and the seem to be fine now.
