  • Brake and Clutch Fluid........

    I am finally at the point in my four-year project that I'm going to be putting fluid in the clutch and braking systems......everything is new, no trace of old fluids. I see that DOT 5 is recommended by many for the clutch, but what is recommended for the brakes. Your thoughts, please.........

    I've been using the same Dot 5 Silicon fluid in my brake system for 40 years. ESPECIALLY brake system. Got tired of having to repaint the servo and body panels under it everytime the Girling paint remover escaped.

      I switched everything to DOT 5 when i rebuilt both hydraulic systems a couple of years ago. The clutch hydraulic parts were all new, brakes got rebuilt MC and calipers, new rear cylinders. I flushed the old fluid out of the brake lines, then did it again after a couple of drives just to be sure. No problems with either system since.

        Apple Hydraulics recommends the DOT 5 that Moss Motors sells. Not sure why, but that is what they told me when I had them rebuild my brake MC

          If you're not in the habit of checking for things under the hood, then it might be better to go with the silicone 5.0 brake fluid. If the seal goes out on the brake MC, then it's just a matter of fixing the leak and washing down the area under the leak. Or so I'm told...
          Me? I'm old school about certain things. Still use DOT 4 in both brake and clutch systems. Kind of a contest to see if I can beat the odds. But I do hedge the bet by having a small, hidden reservoir Gorilla Glued on the brake booster, under the MC, to trap any leaking fluid. Holds about an ounce. Need a flashlight to see if there's anything contained. But like most backup systems, never needed unless there isn't one!

          Yes. My oil filter is original, as well. Figured out how to change the filter without losing a drop of new oil when remounting, and only change the O-ring in the block about every two years. I'll shut up now, or else I'll start on my original seat belts.

            When I rebuilt my clutch master and slave recently, I went with the DOT 5. (Still have DOT 4 in the brake system)

            DOT 5 seems to bubble more during the pour. Something I didnt care for.

            We'll see. I probably need one more bleed anyway.

              Been running DOT5 in both systems for 9 years - no problems. I just bled it through the system until I saw solid purple coming out. You are starting new so it should be easier. Recommend pouring it down a rod like you did in chemistry class to keep it from splashing and making more bubbles than neccesary.

                Can of worms... but I have used both DOT4 and DOT5. Swapped my 6 by just draining the DOT4 blowing through with compressed air and running 2X the amount of DOT5 through. That was 4 years ago and works fine.. I'd challenge you to feel a difference (some say it gives a softer pedal, but I am not skilled enough to feel it).

                  I switched to silicone (DOT 5) a couple of years ago. Got tired of paint getting destroyed by Dot 4.

                  I notice no difference whatsoever.

                  Both clutch and brakes are equipped with DOT 5.

                    When I did a frame-off in 2012/3, I replaced or rehabbed all of the hydraulics and took the opportunity to switch to DOT5 throughout. The car already had a hole down in one corner of the footwell as a result of leakage from the brake M/C, paint loss and rust, so I wasn't going to perpetuate that process. Unlike DOT3/4 which are hygroscopic (absorb moisture), DOT is prone to absorbing air and bubbling. I let the new bottle sit for a couple of days and carefully open it without shaking it up before I add it to the system. Some pour it down a rod - myself, I just pour slowly and smoothly, bleed the system, and then bleed it again a couple of days later.

                      After expensive repairs and restoration fixing damage from factory fluids and standard battery I went with Dot-5 silicon in brake and clutch systems. And an optima battery in a plastic box. No problems 15 years.

                        Hey Todd,
                        Glad to hear you're moving forward on the build...myself, I used DOT 5 in both clutch and brakes. Wish I knew about pouring down a rod back in 2014 !!
