Any way to prevent the pistons getting dislodged on the single piston rear disc trucks? Mine is an 02 and I would love to not have to get new calipers/lines and screw my new rotors.

 

The piston won't push out when you take the caliper off. Just push it back in to make room for the new pads. Use a c-clamp and an old pad. Or you can buy the compression tool pretty cheap. Either way its pretty straight forward.

 

I know how to do them..I am just asking if there is a way to prevent the piston from siezing up after its pushed back..gm's are notorious for the pistons dislodging after pressure is reapplied. I personally know two vey mechanically inclined people that have had to buy new calipers to just doing a regular brake job.

 

ive changed many of brakes and never had any seeze up on me

 

Thanks for the replies. Anyone ever actually hear of this happening? Youtube silverado caliper sieze and there are plenty of people with problems after brake jobs and some just randomly

 

I had my rear dual pistion calipers (at least one for sure) start to stick after changing the pads. I dont have really for sure sound advice on how to keep it from happening, but if i were to do it over again id try cleaning the pistons really good before pushing them back in and crack the bleeder so there isnt any pressure behind them. also try not to bottom them out excessively.
But after reading all the issues out there its still a gamble imo if they will stick.. Only one way to find out..lol
No big deal if they do, calipers arent that hard to change in the rear and not extremely expensive

 

Hmmm. Never heard of that one happening before. Ive done quite a few brakes on all kinds of crap at the shop and not a problem with pistons getting stuck from being presed back in.
