Yes, it's generally recommended to bleed the brakes before putting the hub back on, especially if you’ve replaced brake components or opened the brake system. This ensures that any air trapped in the brake lines is removed, which is crucial for proper brake function. Bleeding the brakes after reassembling can be more difficult and may not achieve the best results. Always follow the manufacturer's guidelines for your specific vehicle.
On the axles, just before the hub and brakes.
I got so far and can't get the hub assembly off. I tookthe disk brakes off. Took the brake holder off. Removed the 4 bolts from the back that looks like it is holding the hub but the hub will not come off. Is it pressed in? Do I need to remove the drum brakes and pry off the hub?
Bleed all the brakes first to make sure no air in the lines and then on the back brakes if they are drum brakes on the inside hub you will find 2 rubber push in plugs that you take out and if you look in the hole you will see a gear wheel, either use a screwdriver or a brake spoon that you get from the auto store and turn the wheel upwards until you feel the brakes dragging a little on the drum, of course you have to jack the back end of the car up to do this so both wheels are off the ground and turn each back wheel by hand as your adjusting the gear wheel to get it set properly.
There are no bearings in brakes, but the hub has large ball bearings
on the back behind the wheel hub should be a gear looking thing that moves turn it slowly until fully ajusted
There are 4 sensors on the 1995 Chevrolet Blazer. The 2 front for the Disc Brakes is behind the rotors on the hub. The inside hub has gears and the sensors are above them. On the rear, where you have Drum Brakes, the sensors are on the back of the Drum Brake Assembly, next to the bleeder screws.
Take off the wheel and the brakes. There should be a cap in the center of the hub, take that off. There will be a nut with a cotter pin through it, take out the cotter pin. Unscrew the nut, take out washer. Slide hub off spindle. Knock the back seal out of the hub. Clean the hub, pack bearings and hub with grease. Place new back bearing back into hub, then lightly tap seal into hub. Put the hub onto the spindle. Put in front bearing, washer, nut, cotterpin, and cap. Replace tire.
The different types of brakes used in bicycles are rim brakes, disc brakes, and coaster brakes. Rim brakes use pads that press against the wheel rims to slow down the bike. Disc brakes use a rotor attached to the wheel hub and calipers that squeeze the rotor to stop the bike. Coaster brakes are found in the rear hub and are engaged by pedaling backward.
To replace the rear hub assembly on your vehicle, you will need to first lift the car and remove the wheel. Next, disconnect the brake caliper and rotor. Then, unbolt the hub assembly and remove it. Install the new hub assembly by reversing these steps. Be sure to torque the bolts to the manufacturer's specifications and test the brakes before driving.
The grinding could be coming from the rear brakes.
the only difference to changing brakes with a full floating axle , is that you dont have to remove the axle the brake drum will come off the hub with out removing the axle. you may have to get underneath and back off the brakes to free it up enuff to move the drum
Coaster brakes on bicycles work by using a mechanism inside the rear hub that engages when you pedal backward. This action causes the brake pads to press against the inside of the hub, creating friction and slowing down the bike.
