Brakes are hard to push down to stop? - 1998 Chevrolet S-10 Pickup

If you mean that your brake pedal is hard when you step on the pedal like has resistance , than it sounds like you need to replace your brake booster. Unbolt master cylonder from brake booster. Leave brake lines attached. Inside car remove the pin going to the brake booster. There are four 15 mm nuts that hold the booster to the floor board, you will have to remove them with a swivel 15mm socket. Remove booster and replace in reverse order. Leave comment if this helps.

Hi- Check your large - very large black hose that goes to the Power steering booster. The booster sits right in front of the driver under the hood and is black - round and large. It has a hose that goes to it from the intake area of the truck - this hose has to be - in good shape - capable of holding a vacuum and attached at BOTH ENDS.

Replace if necessary.
This should fix your problem

please vote me 4 hands up of this is a fix for you.

Thanks
