Master Cylinder Heat Shield

[Benny Grumer]

Friend,

I strongly recommend adding an isolations board above the muffler attached to the floor board. – read the book "floor board on fire"

It will deep you cool ….and prevent caching fire on old floor boards..

Benny,

 

That’s true for all braking system (other than those with silicone fluid). Brake fluid is hydroscopic, it attracts water. The cure is to change the fluid every two years. Heating the master cylinder is not a good idea as it will shorten the life of the seals.

The rust will accumulate on the inside of the brake reservoir due to water entering the reservoir. Heating the brake oil will evaporate the water….

Putting an heat shield on the reservoir is not a good idea. The original heat shield allowed some heat from the exhaust muffler to reach the oil container …..

The original shield should be kept.

Consider the tradeoff -  rust in the main brake cylinder  or replacing the rubber parts every five years or more.

On the TC the main brake cylinder is the lowest part of the brake system. water will accumulate especially when the car is not driven  frequently.  

Brake system rubber will withstand 100 deg. C  . The original heat shield will protect the brake oil container from direct heat radiation.

I'll back that Benny,    I had a floorboard burn through and the seat under me well on fire many years ago now, but it's the sort of thing you remember well !   Clive   m mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

Benny,   Traditional brake fluid is designed to absorb any water entering the master cylinder in normal conditions, and providing correct maintenance of changing the brake fluid every 2 or 3 years is carried out there should be no problem.   Silicone fluid does not absorb water, so this can be, and is,  a problem if you use that fluid in our open to the air systems (Silicone fluid was designed to be used in totally enclosed systems).    On top of the rust, any water in a silicone system will freeze solid if it's cold enough in winter.   If the master cylinder gets hot enough to evaporate anything, the the rubber seals will be damaged and ultimately, if not immediately, fail.   So Keep the Master cylinder shielded form the exhaust.   Clive m mmmmmmmmmmmmmmmmmmmmmmmmmmm

Neil,   TC2656  would have originally had the shield fitted.   Yes, fit one, it will not affect the corrosion aspect, and will keep the fluid and rubber seals cool within  safe operating temperatures.   Clive m mmmmmmmmmmmmmmmmmmmmmmmmmmmmm

Benny,

 

My original master cylinder was 66 years old and had stood in a damp garage for 48 years. The rust inside was minimal, only slight surface rust. The bore was corroded which is why I replaced it. The water that gets into brake fluid is absorbed into the fluid and will cause rust if allowed to build up. However changing the fluid every two years, which is a manufactures recommendation will stop the problem. Whilst the rubber components will withstand high temperatures, constant heat will cause the rubber to go hard earlier than it would otherwise do. The high temperatures are not constant unless it’s a race car.

 

I’d rather change the fluid every two years than rebuild master cylinders.
