[Tigers] Brakes biting

[Wayne Pierzga]

Hi Jay

I was not aware you were using SS braided flex lines. If I recall these use a 'plastic' tube to carry the brake fluid. I don’t think these tubes delaminate/collapse like OEM rubber as they deteriorate.

So, I have another suggestion you may want to investigate. Is there an in-line vacuum check-valve between the carb and brake booster? If so this may be sticking and could be the source of the intermittent problems you describe.

Cheers
Wayne

I’m starting to suspect the hoses more.  There was another incident that was a bit different, and now that I think of it, points more to the hoses.

As I said before, as I was coming to a stop, with my foot on the brake, at the last second before coming to a complete stop, it seemed the brakes bit a little harder - like I pushed the brakes a tiny bit, even though I didn’t at all.  

My initial assumption was that there was a bubble in the rubber hose, increasing pressure.  But I discounted that since it stopped immediately when I lifted the pedal.  When I have heard about this before, I recall that the bubble kept the pressure up even after the pedal was released.  But every situation is different.  

This other incident was also at very low speed, just after I lifted the brakes and was coasting forward, I got a feeling like I was taping on the brakes repeatedly and the wheel was chirping.  It was very strange.  I don’t know the details to give more help on that.  

One other factor, I have braided stainless hoses, that are smaller OD and ID than stock rubber hoses.

I didn’t notice anything at speed or during braking.  Just that last moment.  But once I lifted, it always stopped.  Then at one point, it seemed like it was biting a bit more.  Again, the second I lifted off the brakes it was fine.
