Flush convertible top cylinders

Recommended Posts

i want to flush the top cylinders of brake fluid to use ATF. i know some kind of alchohol is used but cannot remember which type. also, is that not a good idea for the seals in there? appreciate any advice.   thanks,  capt den

Don't know for sure but it's probably denatured alcohol which will remove moisture from the system by absorbing it and then evaporating . Seeing that it's not a life critical system like brakes, you could probably just flush with enough ATF to effectively remove/dilute the brake fluid and moisture from the system. BTW - here is link to a film strip on servicing convertible tops from the 1950 Chrysler Master Service Technician Conference. Watched it the other day and there are some good tidbits regarding filling the system and so on:  MTSC Convertible Tops

My 55 Ford used brake fluid too so all I done was to take it completely apart and blow out the lines and moved the cylinders to remove all the brake fluid and reassemble,I never flushed with anything and its been 10 years and so far no problems.

i do not wish to did-assemble the cylinders, but i can take them out of the car and clean and flush to get all the brake fluid out.the film that vintage sent shows how that can be done. the new pump i bought recommends ATF, but brake fluid is also acceptable. the original pump used brake fluid. the mopar film shows the exact system i have, so it is a tremendous help. i never knew how all the adjustments worked. the top mechanisms were always a mystery. not any more.  thanks to all who responded with advice.  capt den

I did not take the cylinders apart but removed them from the car so I could get all the fluid out and also removed the lines from the car too so not to make a mess in the car.

super interesting topic..

Would someone know if there are differences between convertible- hydraulic parts from the 50-53 CRANBROOK model  versus the '54 model? different pumps or pistons or are these parts interchangeable. At MTC convertible tops they do not know either... has somebody info/documentation/ partnumbers on these items...?

thanks!

51-52 Motor cable driven...

53-54 I believe Motor hydraulic

The MoPar parts books will ID

Also Hollanders
