I have never had the car off of jack stands. Rebuilt all 4 calipers, pedal cluster & installed a fresh 17mm MC and 4 new flex brake lines. Set the venting clearance on the rear brakes and the pedal clearance is also good.
Bleeding the brakes I get good fluid movement and no air bubbles from all 4 corners. Probably have been around the car 10 times now. The last 2 times around were the best as far as no air and lots of fluid per pump...using my wife to press the pedal. Rear brakes grab and hold. I cannot move them by hand. Front brakes now grab, but with just a bit of extra work I can move the rotor with my wife holding the brake pedal down. My pedal is not firm and does bottom out. Then if the key is on, the dash warning light flashes at the bottom. Is that how it works? the main question here: But why do I still have a weak pedal and little or no front brakes? Do I just need to get it moving and operate the brakes? Thanks, Clark |

WARNING about OLD-NEW parts: If I had had the confidence to dismantle my "been sitting on the shelf a while, still in the box" NEW master cylinder, I might have found this:
it is the MC section that pressurizes the FRONT BRAKES. You know the ones that I spent 10 days dicking around with. (IMG:style_emoticons/default/KMA.gif) Once I got it out, I really did not see anything. But once I touched it, it felt hard. I squeezed a bit and it cracked between my fingers. This is a 17 mm MC, so none of these innards are available? Would love to hear that there really are some seals available. |
