Replaced Booster - Kung Foo Grip Brakes
Posted: Fri Apr 30, 2010 1:55 pm
Happy Friday all...
After 2 years of driving with a leaky booster, I had it rebuilt by the fine folks at H&R and installed it in my '73 Bus last weekend. Took it for a drive this afternoon and right away noticed the AWESOME braking power.
Also noticed some interesting squeaking as I drifted up to the first traffic light. Drove about 1 mile and looped back for home.
All the while, the performance of the normally peppy Boston Bob 2.0 seemed somewhat subdued..
About a quarter mile from home, going downhill I noticed the bus did NOT want to coast freely...and increasingly was slowing down....more gas....barely...barely...able...to...accelerate...straining.....CHT jumping up over 400..spock...help me....spock..
Got it into the driveway and shut her down and was hit with the fine aroma of really hot brakes.
So, my thoughts are:
The calipers or brake cylinders, upon seeing forces they've never seen (from the new booster) have gotten stuck in the full on position.
I screwed up the distance that I screwed the brake pedal actuating shaft into the nose of the booster. I will revisit the Bentley spec, but the pedal did seem to be higher than before....
I am putting my money on the second item above. Won't have the opportunity to look at it until Sunday..so any thoughts you all have would be helpful.
Thanks,
Scott
