Gully Posted September 7, 2023 Report Share Posted September 7, 2023 I've had the two individual ones the seller produces for the GT6 sat on a shelf in my shed for about 5 years now... Gully 1 Link to comment Share on other sites More sharing options...
68vitesse Posted September 10, 2023 Report Share Posted September 10, 2023 Don't understand how they work, if the master cylinder leaks from pushrod end it still leaks down the pedal, if it overflows or you are careless topping up the bolts would need to be sealed, difficult with lock washers. Stripped paint both ways unless using silicone brake fluid. Regards Paul. Link to comment Share on other sites More sharing options...
johny Posted September 10, 2023 Report Share Posted September 10, 2023 Noooo they work by covering up the damage thats going on to the paintwork underneath - its a case of what you cant see doesnt worry you😊 Link to comment Share on other sites More sharing options...

I found this difficult to believe so I poured some DOT 4 brake fluid into a small shallow dish. I then placed a lighted match in the dish. The match went out. I did not repeat the experiment with petrol as a control. I then soaked a small piece of fabric in the brake fluid. This did ignite and continued to burn until all the fluid had been consumed. This would suggest that the flammability of brake fluid is more similar to that of paraffin. The quoted flash point of octane, a major constituent of petrol, is about 13 deg C. the quoted flash point of glycerol, a major constituent of brake fluid is 199 deg C.

dougbgt6 Posted September 10, 2023 Report Share Posted September 10, 2023 Dripping it on your exhaust! Might get more of a result. However, try silicone brake fluid, no paint damage, no catching fire, no need for drip trays. Doug Link to comment Share on other sites More sharing options...
68vitesse Posted September 10, 2023 Report Share Posted September 10, 2023 As above. A quick Google search indicates that a car exhaust temperature can exceed the spontaneous combustion point of brake fluid. Regards Paul. Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 11, 2023 Report Share Posted September 11, 2023 from my years drip petrol on the exhaust and it just fizzes away , drip brake fluid and kaboom it lights immediately there was a period of modern designs that had strong shielding of the fluid reservior to protect from fire in an impact crash .

GrahamB Posted September 11, 2023 Report Share Posted September 11, 2023 If, when you depress the brake pedal, a large quantity of fluid is spayed onto the hot exhaust system, the possibility of fire may not be your primary concern. Work on the braking system is usually performed when the vehicle is stationary and the engine is cold. Non silicone brake fluid is flammable but more similar to paraffin or light oil than petrol. 1 Link to comment Share on other sites More sharing options...
JohnD Posted September 11, 2023 Report Share Posted September 11, 2023 While a lighted match next to a pool of petrol is a definite RUN FOR YOUR LIFE! signal, the old cinema trope of the cigarette end is not. I think the Mythbusters proved this. The petrol puts the fag end out! Link to comment Share on other sites More sharing options...
PeteH Posted September 14, 2023 Report Share Posted September 14, 2023 My understanding of combustion is that it is the Vapour gas that actually burns. We had to heat marine heavy fuel to over 80C before it would even pump. And in excess of that to burn properly. It’s largely how quickly the fuel vaporises that governs the rate of flame propagation. Which is why fuel injection is by and large more efficient. Always assuming the ratio of fuel to oxygen is within the upper and lower limits.

johny Posted September 14, 2023 Report Share Posted September 14, 2023 yes remember the old fire triangle: you need fuel, oxygen and heat for combustion? Difficult for any liquid or solid to get into good enough contact with oxygen to burn so the most efficient method is to atomise or pulverise each respectively and then ignite them...

Chris A Posted September 14, 2023 Report Share Posted September 14, 2023 I belive that if you dropped a burning match into a dish of petrol the vapour will burn but the match goes out in the liquid. I'm not going to try it petrol is far to expensive at present . . . Link to comment Share on other sites More sharing options...
johny Posted September 14, 2023 Report Share Posted September 14, 2023 yes you could try it in your petrol tank and its very likely that apart from the small(?) flame out of the filler the match would go out once dropped inside* * I claim no responsibility for the accuracy of this information and will not be held liable for any damage or injury caused by anyone stupid enough to test it.

This changed my mind: I was with a small group of people watching the start up of a very old and rare motorcycle. It had been running briefly earlier, so the exhaust manifold was still a bit hot. A very slight leak from the fuel tap allowed petrol to drip onto the exhaust manifold. What happened next was just so fast - suddenly there were rapidly growing flames lapping the underside of the fuel tank… Fortunately, a large foam fire extinguisher had been placed next to the bike as a routine precaution. This meant it could be used almost immediately, and a brief blast was sufficient to put it out almost in an instant -only a matter of seconds after the first flames had appeared. . If someone had needed to ‘go and find’ an extinguisher,I am sure the outcome would have been very different.As it turned out, though there wasn’t even any visible damage to the paintwork.
