Replacing the Brake Fluid

[MaynoothMarauder]

Unfortunately i recently added some brake fluid to my 86 Argo Magnum during the holidays and only recently realized that I should have used the DOT5 product. After about 20 minutes of driving I can't brake the left tracks (which is where I topped off the fluid). I have read a bunch of threads and I think this is my problem.
I just ordered new seals (since one is cracked). Does anyone have a video on bleeding the fluid (RD mentions one but I cant find it) or can you give me step by step. I am new to the forum and new to working on argos. thx in advance :e

This is the only Brake Vid I have, and it does not go into HOW to bleed brakes, it shows how to rebuild them. It may be of interest to you.

I would recommend that you clean/flush the wrong brake fluid out of your systems, only DOT5 is rated for the Argo Brakes.

You might get away with just purging the brake system with the correct Brake Fluid.
You will need a short piece of rubber tube (about 8"), a small bowl, and some DOT5
Fit one end of the rubber hose on the bleed nipple for the brake caliper, and run the other end into the bowl.
Put about an inch of brake fluid in the bowl
Pop the top off your Master Cylinder
While holding the rubber tube pinched with your left hand, crack open the bleed fitting with your right hand.
Keep holding the rubber tube pinched, put down the wrench, and slowly pull the Brake Handle.
You will see/feel the brake fluid pushing through the rubber tube into the bowl.
Keep the end of the rubber tube submerged in the bowl of brake fluid
keeping the tube pinched, let the brake handle return to the dash. (By keeping the rubber tube pinched with your fingers, this forces brake fluid from the master cylinder to to flow into the calipers, instead of drawing air/old fluid back through the rubber tube.
Keep pumping the brake handle, each pump will push old fluid into your bowl and draw new fluid from the master cylinder.
Top up the Master cylinder as the level drops, carefull not to create bubbles.
Keep purging through untill you have pushed all the opd fluid out, and them tighten the Bleed Fitting on the caliper
Your brakes are purged
Pull the brake handle a few times to "Pump Up the brake"
Top your fluid in the Master Cylinder, put the cap back on.
Remove the tube and bowl of old fluid

You should be ready to start the second Caliper

Should change out old Brake Fluid every 2 yrs
Hope that's clear

Auto Marine, Bumper to Bumper, Northern Metalic, Canadian Tire, ect. Just about any Auto Parts store should have it.
I don't see any reason why it couldn't be shipped through the mail.

would using the wrong brake fluid cause the brakes to over heat and cause brake fade .i have adjusted the master cylinder so that the piston is out so as to stop brake drag but it still fades after a long run and gets very hot . i have a vanguard 2 . i look forward to any replies cheers lukey newzealand

I do believe that DOT5 is non hydrpscopic which prevents moisture buildup in the fluid. If you use something else then moisture buildup can/will occur and this can cause brakes to heat up/fail. I had to use some DOT4 once as I was out and that was all that was available to get me home. Had trouble with overheating on the ride home. Changed it back to DOT5 right after I got home. Drained all the fluid fron the master cyclinder and lines and flushed them with DOT5 then refilled to the proper specs.

Hopes this helps some.
