When those concertina boots were introduced
circa 1980's As the fluid displaced the stoopid boot made the master cyl low level indicator come on (Mitsibishi espescially)

Albeit ANY theory or iriotic tutor that taught ya that crapola CLEARLY has NEVER overhauled a master cylnder or rear wheel cylnder which have **wipe seals **fitted which are a ONE WAY seal and seal under pressure and effectively vacuum back therefore allowing ingress. Sheesh circa 1980's how many damn lasers etc did ya adjust AND have to bleed to get a FULL pedal for this reason? Ever had a master cyl resleeved and the **Compensating port ** NOT REDRILLED? Try and bench bleed dat sucker-L M A O

ha. so they annoy you do they Snoopy. Stoopid boots.
I suppose you just get frustrated trying to get that boot back under the lid and so throw it away huh. it's not needed anyway right. stupid car makers. what were they thinking.

And yeah, I'm sure the night school instructors and the service bulletins were all wrong and stupid.

When a braking hydrualic fluid system HAS advanced due to greenies and Oh Sh**t Happens legislation to the POINT It is akin to a fuel system SEALED and with positive pressure and a warrant of fitness requirement to have it's sealing checked. Then ya may be right But UNTIL YOU APPLY THAT POSITIVE PRESSURE TO THE RESERVOIR Or SUPPLY TANK-As in fuel Ya WRONG
So yeah i like my braken fluid to be a nice colour and low water content. And incidentally when ya motor racing ya actually DO check the water content of BRAND NEW FLUID And know which ones ya NOT USING.

I learnt that on my first block course lol They told us ya could NOT run an engine on CNG and petrol at the same TIME. LOL Damn thang was driven to the course and outside in the parking lot running on CNG in the primaries and petrol in the secondaries. LOL

Never thrown one away in my life But have done MANY MANY fluid changes on them for the SIMPLE reason of water contaminated fluid.

Why do you think they go to the trouble of making those rubber boots concertina Snoopy ?
snoopy221,
Oct 2, 12:45pm
Tell me if ya must But oh please tell me it is on a four wheel disc system with square section master cylnder seals and SOME attempt to prevent hygroscopic fluid attracting water and holding it in suspension as it is designed to do
Or juss fill the sucker with DOT 5 Silicone brake fluid. lol
snoopy221,
Oct 2, 12:50pm
NOTE. DOT 5 Silicone brake fluid
Is NOT hygroscopic.

but dont mix it with dot 3 or 4. dot 5,1 is mixable again with dot 3 and 4 usually motorbikes use "dot 5 super expensive so you can be sure no moron is gona put that in as they want cheap"

My take on the rubber boots, first noticed on HQ. As disc pads wear, brake fluid levels gets lower, boot fills space to stop fluid sloshing about and uncovering the important hole to the m/cyl piston and allowing air in at the wrong time. Taught to me by my night school tutor :oP

Good point and yip Back in seventies and earlier in america But Wait For It. non concertina style
And keericky Dick how many master and wheel clynders bore rusted from water done on those old suckers?

It's to allow the fluid level to drop as the pads wear, without needing a vent in the top of the container that allows moist air to get in. They did and still do use them on common round deep reservoirs.
I was there back in those days when they were being introduced, at a gm dealership, and there were service bulletins explaining it and we were told about it at night school.

Yeah cylinders did rust in the old days. often. because water got into the fluid.
That scarcely ever happens any more.

The only way I can see water getting into a brake system (assuming it is loosely sealed or 'contained' hydraulic braking system. would be via condensation. ie fluctuating temperatures particularly winter where the metal might sweat . Im not even sure this occurs . but I do know metal sweats. opinions anyone?. lol

gm dealership mmkay sadly that explains a lot been there done that spent time with gm and toyota. lol Reality is ya do toyota pre deliveries for a while and ya might find a little problem and it goes back through reports. Then LOL
Keerist damn manager decides if mate wants a commode then we will do the sh**t on it Toyota P.D. about 8 hours easy peasy Commode. 3 WEEKS. All the same damn crapola seen over time while with GM.
