Master cylinder removal '37 coupe


Recommended Posts

Posted (edited)

It's come to that point in this brake project... I've replaced every part (except drums: they were good) in this system over the last twoo weeks. Found only a couple of surprises including a mouse condo built into the frame rail behind the front brake line block! Another surprise was some soldering on old brake lines.... Seems silly to me when lines are so cheap and easy to swap.

Only thing left to come out is the MC. I've searched through threads here and it seems theres a pin either clipped or bolted to the master eyebolt rod, and a couple frame mount bolts. Can this be done with the floor in place on a '37 coupe? Would really like to not have to remove all that.... I have a lift and can get easy access from under or over....

You could possible take the MC out from under the car. Yes there isa  flange that the w two bolts hold the MC to the frame.

 

I know you do not want to take out the floor mat, but it will be easier to get to the linkage and the MC. Since the MC is attached to the frame  everything would be right at your finger tips. I have the 39 Desoto and have the same MC and this is th ebest way to get to it. Also you then get the chance to lubricate the pivot rod and all the linkage.  Keeping the grease fits and the moving parts well lubed is important.  Also with the floor out you can check the trans and emergeny brake band.

You can get it out but Rich has the best advice.  Likely you will twist off some screws but with a bit of heat

 

the stub ends usually thread right out.  Makes it easier the next time when you may want to remove the transmission.

 

Been there done that.... .  I owned a 37 Plymouth for 30 years.

On my 38, I used a MC from a 86 Dodge for a few years, worked good.

 

I later changed the MC, using a 94 Ford Bronco, worked good also.

 

I used the original pedal assembly..

Okay, thanks fellows. Actually, my uncle had a pretty good suggestion today. I'm planning to go theough the motor this summer and don't have plans to use the car once the brakes are done.... The car will be at home when I pull the motor (right now its at the shop) and I'm thinking I could do the MC with the floor out while the motor/trans is out too.... One option....

Still, i might go ahead and get it out this weekend. I have the lift available which is a big help, and the hi/low beam switch needs replaced and I can do that at the same time. Maybe floor out is the way to go. Hope its not too involved.
