help! some brake problems.
I have brake problems on both my 7's.
1st, on my DD ( '89 rx7 gtu). Sometimes while braking, the pedal feels like it has no pressure, like its going to the floor. But as soon as I feel that, I let off and apply again and it has pressure.
The only things I've done to the brakes since I've got the car (more than a year ago) is: replaced the fluid and bled the brakes (a year ago), and replaced the pads (couple months ago.)
Air in the system? Bleed them again?
2nd, on my project ('87 rx7 gxl). I have replaced the master cylinder (new), and brake booster (used). I started bleeding them, rear brakes bled well.
But, the passenger side front is giving me problems.
There is fluid flow through the lines up to the caliper. But there is no fluid at the bleeder screw.
Next, just for kicks, I bled the driver side front, it bled well.
And of course (once everythings back together) the pedal still goes to the floor.
So my guess is that theres a blockage in the passenger side caliper.
How exactly do I fix that without buying a new caliper at first.
And why would a blockage in one caliper effect the rest of the system, (pedal goes to the floor.)?
Is there still air in the system?
Thanks for any info.

Upon further inspection of my ('87 rx7 gxl) passenger side caliper and brake lines, I found that there is a blockage in the flexible line.
That is all, for now.

I was able to clear the blockage from the flexible line using a paper clip. It all flows now.
Still the pedal goes to the floor, but it has "some" pressure behind it.
So I guess ill just continue to bleed the **** out of the system. Until I get good brake pressure.
I hope that will do.
Later.
