The other day I took the truck for a ride and the brakes were soft. I checked the fluid and there was none in the master....
There appears to be a very tiny leak in the front of the master. Not even enough to drip on the floor (I have never seen any evidence of leaking until I peel back the rubber boot). When depressing the brake there is a tiny weep at the front of the master.
All brake parts are new (4 years ago)
Should I have been checking the brake fluid routinely? Is is usual to have this type of leak?
Thanks
Rich

Keep 'em adjusted and check that master cylinder often.

I will need to bleed and adjust before I take her out of storage in the spring. | | | | | Joined: Apr 2010 Posts: 160 'Bolter | | 'Bolter Joined: Apr 2010 Posts: 160 | Just a little tip. I have rebuilt hundreds of brake cyls with good results,but in working on firetrucks I had poor results in rebuilding them.My thoughts are when you over bore the cyl and it sets for long periods the pressure drops off and allows the cup to relax thus it leaks. To verify this I would go by the fire house every week or so and pump the brakes. As long as I did this they would not leak.Just more stuff based on real world expierence. | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | If you have fluid leaking out the boot, the scraper piston that retains the fluid is leaking. You need to pull the master and redo it. You can keep adding fluid but you may pay for it some day. | | | | | Joined: Oct 2006 Posts: 1,847 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 1,847 | yes without a doubt check all the fluids in any machine routinely. That is one of the ten commandments of machinery maintenance (don't ask me what the other 9 are) | | | | | Joined: Apr 2005 Posts: 17 New Guy | | New Guy Joined: Apr 2005 Posts: 17 | just one quick question; does anybody change brake fluid anymore??? after months/years of absorbing water it turns to crap......kev | | |
