POWER BOOSTERS 2 - BT-201A

November 25, 2011 (continued from prior page):
This one comes from Patrick Mulholland in Australia:
Booster installed behind dash Booster installed behind dash
Patrick has tucked his remote brake booster up behind the dash. It appears to be occupying space where original factory radio speaker would be installed. Two hydraulic pipes and one vacuum hose pass through the bulkhead.

Booster installed in passenger foot well Booster installed in passenger foot well
This one is installed in the passenger foot well of a RHD Coupe (notice the correct the gray carpet). Nice job with the carpet cover, but not my choice of location. My passenger would likely be complaining of the obstruction of kick space.

Booster installed in engine bay
This booster is installed in the right rear corner of the engine bay in a RHD MGA. Apparently it was bypassed with a tubing connector after the booster failed. Most booster failures are a result of a split rubber diaphragm in the vacuum chamber. I saw one fail once during a car club tour. The driver had to stop and refill the master cylinder reservoir and bleed the brakes every 20 minutes or so, as brake fluid was being sucked through the servo vacuum chamber into the intake manifold to be burned in the engine. On the third or fourth stop the convoy was collectively running low on spare brake fluid. So we pinched off the vacuum hose with a small ViceGrip to disable the serve, then continued on with manual brakes for the rest of the day.

Remote booster of unknown vintage Remote booster of unknown vintage
Here are pictures of another vintage remote brake booster, also failed. Age and origin of this unit are not known. The owner is considering having one or both of the failed units rebuilt if someone could identify the parts to verify that they are appropriate vintage to be period accessories for the MGA.
