54 brake fluid question (last one)

[Guy M.]

Ive heard of elevation issues as it relates to silicone brake fluid. I live @ 5300 feet ASL and is there any credible concerns? Is this a game changer? Thanks again

I've had problems at high altitude with DOT 5 silicone brake fluid BUT I had exactly the same problem with glycol-based DOT 3. So, I really don't think the problem had anything to do with the type of fluid but was related to something else (what I have never been able to determine). In any event, we used to have a member that hung around here that lived in Albuquerque, NM. He reported that he had used DOT 5 silicone fluid with no problems whatsoever.

I have used DOT 5 silicone brake fluid in 3 solid axle cars and it is great.

The only problem is that it won't remove paint, if you want to use it to do that...

I put DOT 5 in my 60 (at home, elevation 1400 feet) and drove to 'Vettes in the Rockies' in Frisco, Colorado thru Eisenhower Tunnel (elev 11,000 feet) and had a hard peddle all the way. Just avoid air bubbles in the fluid at all costs.

Guy,

There are no elevation issues with silicone fluid. The key thing is to pour the fluid and bleed the brake system slowly (think glacial speeds) so you don't agitate the fluid, causing it to trap air. Do this properly and you'll be fine.

Thanks folks, I really appreciate it. Its done, I'll use the DOT 5 since I have it. Thats really good advice to go slowly when filling the system so as to avoid bubbles. I live in the Denver area and might drive into the hills at some point. I honed the rear cylinders really well but I think I'll have them re-sleeved anyway. Now would be the time for me to do that. I used Apple hydraulics fot the MC and i'm happy with that. Thanks again!!!!
