Bosch 5.1 ESI6-32N Brake Fluid

I've been using it for years now on my and family members cars, some of friends cars. The only exceptions are where people want the cheapest BF possible.
I like this Bosch BF, it's not 5.1 per say but rather compatible and interchangeable with 3, 4 or 5.1.

Thanks. Any brake pedal feel differences? Dealer just did the brake flush and the wife says less pedal force and improved sensitivity.
 
I change BF every 2 years so it doesn't degrade far enough to feel difference in the pedal. We here have 6 months of rain a year thus 2 year cycle, in dryer climate is go with 3 years cycle.
As matter of fact I just did brakes including BF on daughters car yesterday and used this BF.
It was a full day, brakes, ATF, AC refrigerant, some burned out bulbs all on '08 Acura CSX.
 
That seems like fine fluid. A little spendy, but the specs are good. I personally just bought some Lucas DOT 3 for $9/quart. My feeling is changing the fluid is what's important, even if using the cheap stuff.
 
$25/quart? now i don't feel so bad about spending $54 for a gallon of BMW dot 4

@Rockauto $10.09 per qt can.
 
I bet no differences in pedal feel due to a different BF, but due to some air before.

I've got this one. At root the OP asks who visits radioactive waste-sites to collect super-powers.

The OP is in luck... it so happens I glow green. You'd never believe how useful X-Ray vision is; I've picked up others too. I can turn cabbages into light-bulbs, I go invisible when no one's looking, and compare brake-fluids, right down to a one brand of brake-fluid over orange-juice.
And you'd better believe, when it's the one with no air, orange-juice wins.


No, no... thank me later.

Less pedal force = air remaining in the system. If they did not use a pressure bleeder, I can guarantee you that a pneumatic bleeder was used and there is now air in the system.

Am I reading this wrong? When I’ve had my brakes bled perfectly the pedal has required less force and engages right away. Anytime I’ve had air in the system it’s been a less than full, spongy pedal. I dealt with this on some crappy re-manned calipers. No mater what I did I never got the full pedal back.

When a system has air remaining, the brake pedal is spongy.

Spongy = less pedal force required.
 
Gotcha. I equate spongy to more effort to stop the car. I like my pads hitting the rotor as soon as I apply the brakes. I’ve got a pressure bleeder that’s always given me those results. Minus the $450 Powerstop remans that ended up being absolute garbage and I eventually gave up on. I’d have been further ahead to just light my money on fire and saved my labor and sore back.
