Weekend visit to our families while in the army, Volkswagen Rabbit, fully loaded with people and some gear, I was driving. Approached an older exit, the ones that have very short deceleration lanes and sharp turns, pressed brake, felt really sluggish. Shifted down hard, engine screaming, used the parking brake at help, made the turn with screeching tires. The owner (carefully) drove it to a repair shop on Saturday and they found that the master cylinder had a big crack in it. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

Even in times of old :-) I've not had a cylinder crack... sounds like poor maintenance, over or under torquing. I've had the rubber parts start to deteriorate so that you had to "pump 'em up". Had a clutch master cylinder (280Z) rubber go like that while I was away from the house taking my boys to their soccer matches. Stopped at the foreign car parts place and bought a kit (even came with a hone :-), changed it out at the soccer match parking lot :-) Tested the anti-skid braking and automatic seat-belt tightening yesterday, a car pulled across in front of me while I was doing around 45 :-( ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Spice is like a sports car...

The hood blew up, into the windshield at 55 MPH, and on it's way it ripped the reservoir off the master cylinder, and cut the steel tubing. All the modern designs do is make you cocky, then you die. |
