Great question! Others can chime in, but I'll give you my two cents.</p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;"><br></p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;">In my '60, I redid all of the brakes at the point of restoration (master cylinder, hoses, and wheel cylinders (did not need to do lines), and I went with toe good old DOT3 brake fluid. Have not had any issues with water in the lines, or stiffness of pedal. The bleeding process went as normal, no issues.</p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;"><br></p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;">In my '67 Sedan, I only had to replace the wheel cylinders (all lines, the dual master cylinder and hoses were all in good shape) and do a brake line flush. For that one, I again used the DOT3 fluid, and I have never had an issue, nice stiff pedal and no issue bleeding the brakes.</p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;"><br></p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;">In the '62 wagon I just completed, I wound up replacing both rear brake lines, hoses, and wheel cylinders, while I was in there doing the complete rear suspension upgrade (went to the '64 leaf spring set-up). The car came to me with DOT5/silicone already in the lines, and I saw no need to replace it (if it aint broke, ...) so I bought a bottle of DOT5, bled the system as normal, and I've had a nice stiff pedal on the car. No weird issues or problems bleeding the brakes.</p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;"><br></p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;">As to the article you had read, I'm not sure either what it would mean for it to be hard to bleed. Once set up, it's a closed system, and in our arid climate (even Denver is considered a high plains desert), I'm not sure how much of an issue it is.</p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;"><br></p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;">Now, those are the three vehicles I can speak to. Other folks in the Club, chime on in with your thoughts.</p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;"><br></p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;"><em style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 14px;">Ed Halpin, PPCC</em><br></p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;"><em style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 14px;"><br></em></p><blockquote type="cite">On September 13, 2018 at 5:02 PM John Kull via PPCC-list <ppcc-list@corvair.org> wrote: <br> <br><div dir="ltr">Greetings from Grand Junction! <div><br></div><div>Those of you that know me know that I am really new to Corvairs. I am working with my son on a 67 Monza and we plan to replace EVERYTHING in the braking system. I have acquired new lines, hoses, shoes, master cylinder and am rebuilding wheel cylinders. My question is about fluid. I keep hearing folks talk about DOT 5 or silicone brake fluid. The Clarks website seems to push it and I hear that many folks use it on older cars since it will not attract water. It all sounds good but the other day I ran across an article that gave a few downsides saying silicone fluid is hard to bleed and if you live in a dry climate (which I do) that you really can stick with DOT 3?</div><div><br></div><div>So I am asking the club members - what do you ladies and gentlemen use on your cars, trucks and vans?</div><div><br></div><div> DOT 3 or DOT 5 and what does it mean that silicone fluid is "hard to bleed?"</div><div><br></div><div>Thanks in advance!</div><div><br></div><div>JK</div></div>_______________________________________________ <br>This message was sent by the PPCCs mailing list, all copyrights are the property of the writer, please attribute properly.
