Rebuild Caliper assembly paste

[UNC171]

Hey all..

I am planning to rebuild one of my rear calipers on my Santa Fe and I came across this ATE Brake cylinder paste.. Apparently this is specific for rebuilding purposes.. You use this paste to coat the piston cylinder and lube the sealing o ring and coat the dust gasket for easier assemble..

But I can not determine what this ATE paste is mainly made from.. Not sure if it is silicon base, or what!... Its hard to find, as I am wanting to find something comparable...

you can also use new fresh clean brake fluid unless specified by the manufacturer for a red rubber grease.

I've always used fresh brake fluid. If you wanna do a good job clean everything and wash your hands before you put it back together. No debris is important for long life. Put silicone grease or silicone oil where the boots sit in the piston unless it's not the rear twist type. If it's the push type then it doesn't matter much but it's still good to put a layer of silicone on the inside of the boot to keep it supple and do so on the folds on the outside so those don't split early.

I think these sorts of assembly pastes are meant for calipers that aren't going to be put into action right away. Use red rubber grease or if you don't want to overthink it, brake fluid.

Brake fluid works. Toyota, Honda, Nissan and Subaru all want a red rubber grease to be used, it’s not that expensive from a Toyota dealer.

I’ve heard silicone grease like Dow 111 could be used but I’m not sure if it mixes with brake fluid.

ATE Bremszylinder-Paste has been around forever,the msds do not say much but it's probably made of some glycols.

Similar product is Textar Hydra-Tec :

Neither of these should be used outside assembly work (they are NOT suitable for caliper pins etc).

P.S. Found some :

Had a bit of a tough time finding the Conti/Teves/ATE product a while back and bought a tube of PBR Rubber Lube that has lasted for years. The PBR was easier to get. If you are rebuilding calipers, masters or slave cyls, use the rubber grease.

This, except I also feel the same way about the red rubber grease, not needed unless the caliper is going to sit around for weeks, then you want something more viscous than brake fluid so it sticks around till you're ready to put the caliper into service.

I coat the piston bore and mating surfaces with silicone grease. Any moisture that enters the braking system is through these sealing surfaces. Brake fluid and the ATE brake cylinder paste are alcohols, which absorb water. Silicone paste acts as a barrier to moisture, allows good brake function, and will not affect the brake fluid.
