2ndGear, your obvious lack of knowledge is a bit disturbing for doing "thousands of brake jobs". Old brake fluid contains sediment and contaminates especially as the fluid ages. All that gunk sinks to the lowest points, the calipers. When you don't bleed them you're pushing that garbage back up the line. Unless you have no other choice you're just being lazy by doing that.

Brake systems are not perfectly sealed from the atmosphere or oxygen free. They keep air transfer to a minimum with diaphragms but none the less every time you step on the peddle the system vents otherwise the master would implode.

Good luck selling a brake flush to every brake job customer.

I thought everyone on GJ agrees brake flushes are pointless?

I've never worried about what's in the caliper either. If there's that much **** in your calipers you have other issues

Oxygen free environment? Not a chance. *yawn*.

Yes, the master cap lets in oxygen.


No, the fluid doesn't constantly tumble and flow enough to push fluid back to the master to absorb said oxygen. Pull water out of the air? Sure, it's hydroscopic. Rubber parts also contribute to blackening fluid.

Like I said, how are contaminates/gunk that sit in the system 100% of the time, suddenly going to destroy components when a caliper is compressed?

If only.

Me too!

On my own vehicles yes, that's all I do is replace the piston seals/boots and fill up with dot4 on every new purchase. It is Soooo much smoother in operation. I love the feel of perfect brakes. You notice it greatly on motorcycles. Gives you great confidence. I've had calipers that you would think were fine until you open em up. The nastiest **** gets behind the piston that a flush will never take care of.

Depends where you work and what you're working on. Unless you wallet flush a pressure bleed takes about 5 minutes. Longer if you want to go through the trouble of cycling the ABS modulator but that's not necessary. Brake fluid is cheap and should be largely replaced every 4-5 years at minimum.

Good thought... Following the manufacturer's recommendations is often good advice, especially regarding brake fluid replacement and flushing. I believe everyone agrees and understands that just about all the fluids in the average vehicle eventually degrade to the point of contributing to unplanned failures. Getting the average car user to replace brake fluid or flush/replace and pay for it is often a struggle I suspect. In the mean time thousands of brake jobs are done each day by pushing the piston(s) back into the caliper..

I'm only doing the occasional brake jobs for personal vehicles myself, and found that a C Clamp suffices well for my purpose. I can see and appreciate the utility / productivity of the other tools that have been shared on this thread.

It's also another $100 on top of a $300+ brake job.

Never said it would cause a failure, I said it was very lazy. Replacing fluid as it ages is simply a good idea regardless of where it is. Coolant, differentials, transmission, even power steering when it gets old enough. I don't subscribe to the wait and see philosophy with any of it. Even without mechanical lubrication properties lot of the fluids also condition and keep the seals healthy, as it ages it loses that ability.

It's also another $100 on top of a $300+ brake job.

As I said, depends on where you work. Without cause (stuck bleeders) charging an additional $100 for that would be a wallet flush especially when you're already charging a price for a brake service where it should already be factored in at a discount. I get that many places profit off the customers naivety in those situations but that's besides the point.
