M35a3 brake fluid

[tx.fireman1525]

My fire dept just bought 3 M35a3's, and we are needing to do some work to the brakes on one of them. What type of fluid do we need to put back in there?

Dot 5

Best bet is to find some from a surplus dealer in gallons. Auto parts store prices are insane for the stuff.

In case you didn't know, [FONT=&quot]DOT 3 and DOT 4 specifications are for glycol based (regular) brake fluid, while DOT 5 is for silicone based brake fluid[/FONT].

Another local VFD used regular brake fluid in their deuces and eventually completely fried the brake systems in both of their trucks.

We get DOT 5 from NAPA and we've also gotten some 5-gallon buckets from the local National Guard.

DOT 5 silicon brake fluid
MIL-B-46176
MIL-B-46176B

[FONT=&quot]Also do not use DOT 5.1 either.....

Hope this helps.......

You might pull one of the wheel brake cylinders on each vehicle and evaluate how much brake work each needs. Came as a big surprise to me.
RGRG on the surplus DOT 5 - you can't afford DOT 5 from the local auto parts store.
