Given your signature, I just had to.
Getting back to the subject matter- you seem to be confused regarding the construction and function of master cylinders. 'Open' master cylinders (not used in many decades) exposed the contents of the reservoir directly to air via the vent hole in the cap. Closed systems (as we see on all modern cars) have a diaphragm inside the reservoir or cap that isolate the fluid from the air. In that context, the system is sealed. All systems have a vent of some sort to allow air to replace the fluid as the level drops due to pad wear, so the air (gas) never rises above ambient in pressure.

No need to remove or loosen the cap accordingly.
I still wonder why we carry on with fluid changes at a 2 year interval with modern cars given that the fluid is not exposed to the dirt and moisture.
Now, lots of people drive every day with old brake fluid. They don't use the headroom because they don't brake that hard ... most of the time. On a panic stop they won't have the headroom and they'll likely never know that they could have had it. All they know is they now have an at fault "accident" on their insurance record to moan about. BTW, there is no such thing as an "accident" in my mind.
Doug makes a good point about not flushing junk from the caliper backwards and possibly contaminating the ABS stuff. Every time I've flushed fluid on a system in good condition, no junk comes out- just old fluid. Failed calipers or wheel cylinders is a different story.

I think I know what you're getting at (but insert "almost" before "no").
Some accidents are beyond the driver's blame (hit by a part falling off an airplane, say).
I think it's a good point, though - ought to be part of the driving test...
I'm aware I make mistakes when driving, kinda kick myself when I do, could cause an accident (viewed from another driver's situation). Probably many people mix up "mistake" and "accident".

The strategy I adopt when an oncoming vehicle is going wide on a narrow street is to come to a full stop if need be. Pretty hard for the other driver to argue if he sideswipes a stationary object.

do you work for a injury lawyers by any chance?....why is something always someone's fault?...accidents DO happen...fact of life...you can't go round blaming someone else whenever you trip up or cut your finger. This blame culture thing is wrecking this country!
As for changing your brake fluid, yes it should really be done to the manufacturers recommendation in my humble opinion.....but if brake fluid really degraded so quickly, to a point where it was dangerous and would impair braking so drastically, then it would have to be changed at every MOT. Lots of other factors have to be taken into consideration when discussing brake efficiency, not just the quality of brake fluid. I'd like to think that one of the biggest reason for brake failure would be the rubber brake hoses splitting or a rubber seal.....who would you blame for that one?...should be strip our brakes down every year just to make sure....??

bloody ambulance chasers....anybody hear about some of these low life ringing people who are in hospital, straight after an accident, seeing if they want to claim??...i'd say yes, come on round to see me...then when he arrived beat the c**p out of them and then claim off them for making me do it....

Help needed
The brakes on my 2003 jaguar s type are squeaking a lot so i think its time to replace them. I got this car about 3 months ago and this will be my first time doing any maintenance to it. Can someone recommend any good and reasonable mechanics that are experienced in Jaguars? I live in Orange County.

Hi All
I have changed the rear discs on my 2005 S type 3 times in my ownership and never removed the fliud cap or had to reprogramme the EPB, why make the job harder, The fluid ammount is minimal and the system is not under any pressure at all. As for the EPB pump up the brakes after fitting the pads with ignition off, All done

What's the best way of disengaging the EPB to get the pads and caliper off?
