Long term results without brake system flush

[Bfromla]

I am what you consider an "Oldtimer" and in that many years 67 so far never have I replaced the brake fluid in any on my cars or motorcycles just because. The only semi valid reason is if the fluid is somehow got contaminated or has absorved moisture from the air. Unlikely under most normal conditions. On racing bikes they service their entire brake systems after each race because they overheat with the high stress of braking at higher speed so I see why they will change the fluid every time or at very low intervals. Most Spyders with brake problems are because the quality of many #BRP products are cheap junk in general. It has nothing to do with having ABS. Most new motorcycles and cars have ABS. Costing $300 a pop I see why dealers highly recommend to get it done yearly or more often if po$$ible! It is all about the money! Not buying it!

Simply DIY & save. Unfortunately fluid does break down & or get contaminated

I installed speed bleeders on my Goldwing and made brake bleeds and fluid replacements a breeze

My 2017 RTL bought new in March 2018, has 47000 kms on the clock. The fluid was replaced last Friday when in for the 45K service. The brakes had been a little "spongy" prior and the flush/replacement has certainly made a difference on mine. It reminded me how these "slowly developing over time" things like brake fluid degradation can sneak up on you. Interesting point you make though about vehicles not maintained

I am thinking about bleeding the brakes on my 2015 Can Am Spyder myself. I am going to use a MityVac and what I have read it don't seem to be any problem if you do the front left wheel then the front right wheel then do the rear. I am a little afraid of bleeding the VCM bleeder. I understand this could cause a problem without BUDS. I know it would leave a little old fluid in the system. I thought if you can do the front and rear brake calipers then say in another month or so do it again and you would have fresh brake fluid in the complete system. I would like to hear from anyone that has done their own brake bleeding and if they had any problems?

I just changed mine on my 18 F3L. 2 years old and 15k miles. Fluid was fairly dark. We also did my friends 18 Yamaha Venture. Same time and mileage. His was much clearer looking. I used my Mity Vac. Sucked fluid out of reservoir. Filled then sucked out of the 3 calipers. Nice clean looking fluid when done. No using buds.

My 2000 Ford Ranger is on my round tuit list to change its OEM fluid. Maybe when the pads need replacing!
