Brake flush

[SNOOPY]

Actually the Spyder is like other vehicles. The portion that requires BUDS to bleed is the ABS section. BUDS is used to activate the ABS section so it opens up to the rest of the brake lines so the old fluid can get out. Cars with ABS have the same issue. You should be able to bleed every other part of the system just like you normally would.

This is what is confusing about people saying buds is needed?

Ive bled plenty of cars w ABS. Simply bleed until clear at the calipers while making sure the master cylinder stays clear.

I could care less about the couple ounces in the ABS box, is that the only reason BUDS is needed?

Snoopy, it sounded like the BUDS was doing the final bleed, probably to flush the antilock controller. The BUDS is also used in verifying brake pressures.

What you posted is pretty much how I read it in the manual. Myself, I would flush with the manual pedal pump method and maybe do it again in a few hundred miles.

FWIW, this is on my list of items to accomplish. No BUDS here and plan to use the pump the pedal method.

Also, like yourself, I have flushed many cars with antilock brakes and even bleed them with good results. Just make sure it works away from congestion or traffic.

I bled my 2013 RTL several times (4 places LF,RF, R, VCS per the shop manual) and wasn't getting the results that I needed for my hand brake to operate properly without double pumping. So I decided to let my stealerdealer bleed mine for $450 with absolutely no change. The main thing that the Buds does is check the ABS pressure ,so if all you are doing is changing the fluid the pressure shouldn't change.
Turns out my problem was a warped rotor causing a puck to move back causing the brake pedal to have more travel than normal causing my hand brake to need double pumping.

Thanks for all the input, about to try it again.

Wondering now the orientation of the master cylinder, from what I did bleed it looks like the front caliper reservoir is actually towards the back...and the rear caliper reservoir is toward the front.

Let us know the results..........Good Luck.......Hope it all works out for you......

Yes. That is the only reason BUDS would be needed. If you are fine with the 98% new fluid as you would be on every other vehicle you own, then just do it the old fashioned way. It really is that simple.

Okay, just did all three calipers.

Not sure why the suction method I first tried didn't work?

But bleeding by pumping the brake worked fine.

Master cylinder layout is backwards for whatever engineering reason. On the ST the front cylinders fill on the rear reservoir, and the rear caliper fills in the front reservoir.

Definitely had some dirty fluid. I like doing flushes on vehicles rather than have to replace stuck calipers in the future which can be expensive, etc etc.

Also installed my Airhawk seat, hope to try it all out tomorrow if weather permits.

now go find loose gravel, about 25mph, apply brake to activate ABS, now go back and re-bleed, should take care of those few ounces

I can do a little crazy driving to do that.... Lol
