Just a suggestion, check your trailer lights harness for corrosion. They were taking the dash lights down in my chevy.
I just changed one in a 97 blazer Their well known to go out the diafram leaks advance auto sells them $100.
Check the brake light switch.
The power brake booster on a 95 Chevy Blazer is replaced by draining and removing the master cylinder, unbolting the booster, and removing it from the vehicle. A new cylinder is then put in its place and bolted on.
you say alot of prayers!
Master cylinder, is the brake fluid reservoir. It is mounted on the brake booster, on the firewall, driver's side.Master cylinder, is the brake fluid reservoir. It is mounted on the brake booster, on the firewall, driver's side.
check the relays above the brake booster check the relays above the brake booster relay above brake booster
Bad brake booster.
It is probably the brake lights that are on due to a misinstalled or damaged brake light switch.
It is important to have working brake lights on a vehicle. If the brake lights are not working a person should first check the fuse, bulbs and at last the wiring.
No power assist Severe vacuum leak Bad brake booster
Sounds to me like your Vacum booster behind the master cylinder is weak or bad!
It sounds like a vacuum problem. Either you got a bad brake booster or the vacuum line came loose somewhere or cracked when you changed the booster.
