Re: [FWDLK] Brake fluid

[Ron Waters <ronbo97@xxxxxxxxxxx>]

One of the issues with Silicon brake fluid is that it has been known to cause the hydraulic brake switch on the master cylinder to fail prematurely. Failure of this component may result in you being rear ended. Not pretty. A number of folks using Dot 5 have installed a mechanical backup switch on the brake pedal to ensure that the lights will go on when the pedal is depressed.

 

My other problem with Silicon is its incompatibility with Dot 3 or 4. It's easy to forget that one of your cars has Dot 5 and accidently add  some Dot 3 or 4. When realizing your mistake, you would have to completely flush out your system. A pain in the butt.

 

My solution is to use Castrol LMA. LMA stands for Low Moisture Activity. I've had it in my 58 Plymouth for over three years, without any leakage or pulling due to a wheel cylinder freezing up. It's also compatible with Dot 3 or 4.
