The Stovebolt Site Forums The Shop Area The HiPo Shop brake mastercylinder heat question

Hi I have not posted here in a long time. I have a 38 GMC(same as a Chevy)I adapted some original brake and clutch petals to the frame put power disc brakes on my truck. here is my question, how close can my power booster/master cylinder be to the exhaust with out it causing some kind of a heat problem with my master cylinder. ya I know it is a design flaw on my part and I am going to fix it I just need to know how far the minimum distance is so I can fix it right the first time. Also would a heat shield of some kind help me any

To answer your question, I don't know how close is too close but my exhaust pipes were too close for me. I had three areas that concerned me. Master cylinder, the rubber brake hose at my third member, and both pipes are very close to my gas tank. I solved my heat problems by purchasing several different lengths and sizes of fiberglass with a silicon coating sleeving. It's used to protect hydraulic lines on welding robots to keep the sparks from burning through the lines. I split it, wrapped the offending areas of exhaust pipe and clamped it with sst wire ties. Smaller size got used on the rubber brake line.

....have a V8 in my 37 with the m/c-booster under the floorboard. I have the exhaust from a midly hopped up 350 going just under it. I've had no problems in the past 10years.

That works for me Achipmunk, I just know I noticed how close it is and wondered if I was going to have a problem


Thank You

Achipmunk,
I am looking at adding a m/c-booster under the floor of my 37. Was wondering if you had any pictures and or suggestions from your setup.

Thanks

unfortunately I lost a roll of film back when I did the 37. However, you can take a look in my photobucket below and see how the 52panel is set up. While not "exactly" the same they are basically.
If you want, I can slide under the 37 and take a few pics but it is not "store bought" but fabricated by a friend. Back then I did what I had to do but if I would have had the money back then I would have bought the kit.
I purchased the brackets, pedal,booster,M/C (the entire deal) for my panel this past year from Piratejack.net for $207. I do believe they carry a set up for yours but not sure.

Let me know about the pics. I can get some tomorrow or tomorrow night.

I'm experiencing similar problems with my '50.
A V8's a tight fit in an AD,never mind a '38!

I've just ordered a pair of these for the M/C and the area near the starter.

My exhaust is about 6" away from the master cylinder and booster. Been that way for 20+ years with no problems. Good suggestions from the other guys about using a "heat wrap material" on the exhaust. Good for piece of mind.
