The problem I'm having is with my '94 Civic DX. 250k miles.
I was experiencing faulty Brake Master Cylinder symptoms (Brake pedal 8-9/10ths of the way down before resistance/brake engage) So I bought a new BMC today and installed it. After installation I proceeded to bleed the brake lines (Starting with back right > back left > front right > front left [Starting from furthest from BMC ending with closest] Also keeping brake fluid full doing so) While doing so, everything was perfect, up until the front left brake line (Closest to BMC) It had the same hesitation in the brake pedal as every other brake line bleed, but not as much fluid came out, and it also came out at a delay to the pedal being pressed in. (No bubbles either) So after quite some time of trying to figure out why, I gave up and started the car. The brakes felt exactly the same, I could still stop, but NO improvement. Does anyone have a clue as to what's going on? Thank you

P.S - Might I add that my brakes just started to squeal whens stopping, so they DO need to be replaced, but I don't see how this could effect the brake pedal resistance.

 

Did you adjust the rear brakes? Does the hand brake move high before it becomes tight. Did you bench bleed the new master cylinder?

 

Kinked or clogged brake line to the front driver caliper or a bad caliper.

 

I didn't adjust the rear brakes, but I did bench bleed it

What procedures would I do to check to see if either of those are bad?

 

Disconnect the brake hose from the caliper. Is fluid flow still restricted? If not, fluid flow through the caliper is restricted -- clear restriction or replace caliper.
