Silicone Brake Fluid Warning???

Share this page

Well disconnecting and putting the lines in the sun won't work for me. The lines are still in the car (plus they're hooked up to the pressure failure switch body). I wonder if the alcohol flushin is truly necessary, or whether it could cause trouble if I didn't get all the alcohol out. Any ideas or opinions? Also, did you just use isopropyl?
 
Seems to me that if you flush/bleed liberally with the replacement fluid you are going to remove all of the old glycol based fluid.

When I went to silicone based, I just bled the system till the silicone fluid appeared and stayed clean and fresh out those bleeders.

I started with a freshly rebuilt MC.

Keep on.
 
I used denatured alcohol which is available at any hardware store. I did not use compressed air to dry. Brakes have worked well with silicone fluid for 20 yrs in TR3, 8 yrs in TR8. I replace with fresh at about 5 yrs. Had to use a mechanical brake switch from TR4 in the TR3; otherwise, no problems.

Nope !
I've done several cars now by just bleeding until clear purple, and they've worked out just fine.<div class="ubbcode-block"><div class="ubbcode-header">Quote:] or whether it could cause trouble if I didn't get all the alcohol out.[/QUOTE]Oh Yes, Definitely !
Alcohol has a very low boiling point and if it boils - POOF - No brakes !
 
This raises an interesting question. For those who have switched to silicone, how many folks have flushed the system out with alcohol, and how many have simply bled the glycol out until they got nice and pure purple?

Some of my cars have silicone, while others are running glycol-based fluid. No method to the madness -- I simply kept each one with whatever it came with.

B.
 
I replaced everything with brand new, including the lines, so no "old fluid washout" was required on my end.

I did the clutch hydraulics first and after 6 months with no issues or pedal difference, did the complete brake system.
 
On my *8 I have switched and didn't flush. Will let you know if it ever comes off the blocks
