My pops has a 98 Chevy Lumina and well it has to brake cylinders how do i set them back cuz i'm putting new brakes how do i reset the cylinders HELP ASAP

 

if your talking about the brake calipers on the front you have to set them back with a "c" clamp then you have to bleed the brakes

 

The back brakes require a special squeezing tool that also rotates the cylinder while compressing it. Auto-Zone, O'Reilly's, etc can loan you out the tool to do the job. Required on all brake cylinders that include emergency brake.
