96 Cherokee said:Yesterday I cleaned and lubed the rubber boots and pins with a spray on "dry lube with moly". It has a liquid carrier. My first impression is not good. However, I tore the last boot in two while installing it in the hole in the mounting bracket, if that is what it's called. So today I go to Autozone and buy a new set of boots and it looks like my originals have swelled up to at least 50% oversize. Is this normal? It's no wonder they won't keep dust out, the holes in the ends are way to big to seal around the little groove in the pin. Now, after reading another thread here that stated the boots should be replaced on every other brake change, I may be way over due as these may be the originals and I am on brake set number 13 or somewhere thereabouts. So what caused my boots to swell up way bigger than normal. Could it have been my cleaning them with brake cleaner or gasoline?
YES,the rubber or whatever they are made of will not stand up to those solvents.
You need to use a Silicon Grease,not a lithium/moly or chassie lube grease even anti-sieze is not good for the pins and boots.
GM/ AC-Delco makes a lube for this,I don,t know if it is available outside a GM dealer parts dept.It comes in a rather large size can,similar to the anti-sieze can
