Is it safe to use this lubricant on piston boot?

[Pete]

Hello everyone,

Just wondering if it is OK to use this http://www.bendix.com.au/content/high_performance_brake_lubricant on the piston boot when pushing the piston back when changing the brake pads. Also, it’s meant to be applied in the inner boot not the outer boot right?

I ask because I applied a little bit of the lube to the piston boot. After further research, it seems that only brake fluid is necessary. Not sure whether I should try to clean the lube off or leave it there..

When all else fails, read the can or push comes to shove, call the manufacturer tech support in the morning. That number should also be on the can. Oh, and get the name of the person you speak with.

If you’re in the U.S. Phone: 1-800-AIR-BRAKE, option 1 or
1-866-610-9709, option 1 If they can’t answer your specific question about their product, they’ll give you the number of one of their tech support people who can.

Usually the piston dust boot does not require anything.
Spray some brake clean on a rag to clean it.

I think so too. I was just following the brake video eric made 🙂

He said that silicone should be applied to the piston to avoid damning the piston boot when compressing the piston back in. But what if the compound seizes in the piston? could be trouble! So I thought it be better not to use lube/silicone for my next service.

Not to be argumentative, but I’m sure you’d get a 100% accurate answer if you just called Bendix.

the outer boot is a dust boot, and should not be lubricated. if you are rebuilding a caliper then lube the inner seal ring with a light coat of brake fluid is all that is required. if you are replacing the pads only, then as collage man suggest cleaning the outside surface with brake clean and a rag is a good ideal.

You might want to watch the video again because I don’t recall saying you need anything on the dust boot when compressing the piston. What I DID say is you should open the bleeder valve when compressing the piston to avoid damage to the master cylinder. The silicone lube is for the caliper slides NOT the dust boot on the caliper piston.
