Default abs caliper rebuild?

The greenbook says not to break down the front calipers when rebuilding. It further says the bolts will need a "special fluid" and pressure testing if they are broken in half. Seeing that there are no rebuilt abs 240 driverside calipers readily available, im rebuilding both my fronts.


Anyone know what the special sauce is they are referring to? ......or the torque on the caliper bolts?

They probably use a thread sealant. Something like a loctite 592 should work well for you.

The caliper bolts don't need thread sealer, they need thread locker and one that will withstand high temperatures.

The caliper halves have a seal between them that Volvo never sold and the rebuild kits typically doesn't come with them. VP sells them though.

Thanks for correcting me. I wouldn't want those things to have problems from the wrong thread chemical.
