Temperature Of Brake Fluid

[Greg]

Hi guys

I was looking around my engine bay tonight after going for a drive and I noticed that my brake lines that run across the engine to the ABS unit were quite warm. The ABS unit itself was also quite warm. I believe this could be hindering my braking performance and plan on making up a shield / wrapping them in insulating material.

I would be interested to hear from those with experience and/or knowledge on the topic.

Thanks

Greg

The higher the brake system temperature, the more the compressibility of the fluid--increasing the feeling of a spongy pedal.

Considering the temperature of the brake fluid in the callipers, engine bay temp is not an issue. Unless the turbine exhaust or wastegate pipe is very close to the brake lines of course. Then it is best to insulate the exhaust, not the brake lines as they help radiate some heat (hot brake fluid rises).

Thanks for the reply I actually insulated my exhaust recently, so the temperatures wouldn't be as high as they were. I've become obsessed with keeping things cool in my engine bay after seeing how much of a difference wrapping the exhaust made, and thought that the brake lines might be suffering.

If I wrap things in aluminium, is it more likely to be keeping heat out or retaining it? eg i have wrapped the intake pipe in aluminium foil

thanks
