I suspect you have a caliper dragging. This will cause the rotor to overheat and expand, locking up the brakes until it cools down. You could also have a warped rotor that is heating up and getting stuck on the brake pad - either way I would suspect the caliper ( s ) . You can check them by trying to spin the wheels 1 at a time with vehicle raised and brakes warm. If a caliper is dragging and you have a warped rotor, that wheel won't spin smoothly or at all. Another indication would be a pulling to 1 side or the other when brakes are warm. You could actually have a dragging caliper AND a warped rotor. I would start there and to the test to see if this is the problem.
Good luck!

Rear brakes locking up

Have you checked the rubber hose connecting the metal lines with the axle ? The hose may not be allowing brake fluid to return to the master cyl.

Overheating

There may be air trapped in the cooling system. If no air bleed on the thermostat housing, or right beside it, start engine at cold, remove radiator cap, and let it idle until warmed up and the thermostat opens fully. When at operating temperature, shut off the car, check coolant level, and put the cap back on. See if that removes any trapped air.

I replaced my water pump for my 2006 buick lucerne and now theres no heat

Hope you didn't break a nail.

There is a air pocket in the heater core, you just didn't burp it right.

Try this

  1. Open the hood of your car. Secure the hood with the safety handle. If you have a newer car, you should have a bleeder valve on the front of your radiator. Check in your owner's manual for the location of this valve. If you do start your car, open the valve with wrench and let your car heat up. The excess air will bleed out of your cooling system. Keep your car on long enough to give the (trapped air) time to bleed out of your system.
  2. Let your car cool down. Once the car is cool, take off the radiator cap. Did the level of the radiator fluid go down? If it did, it means you bled the air out of your cooling system. Replace the radiator fluid, turn on the car, and let it run. Replace radiator fluid as needed.
  3. Step 3 (above) is the way you will remove air from your cooling system if you do not have a bleeder valve on your radiator. You will leave the cap off the radiator. You will run your car until it heats up. As the air dissipates, the radiator fluid level will go down. You will fill up your radiator fluid to the correct level. Be careful because the heated radiator fluid will be hot. Always wear leather gloves and safety goggles when working on your radiator.
  4. Once the air dissipates and you fill the fluid, shut off the car. Let the car cool down. Once the car is cool, put the radiator cap back on the radiator. You may have to put more radiator fluid in the radiator. The level may fall as the car cools down. Now it is safe to drive your car. You have removed the trapped air from your cooling system.
Tips:
Always wear gloves and safety goggles when working on your radiator.
Radiator fluid gets very hot when heated.
Check radiator fluid periodically.

How do I bleed the radiator in my C70 Volvo ? you can bleed a radiator in a C70 , rite ?..

  1. This method works best if the nose of the car is raised as high as possible. Park your car in your driveway. Let your car cool down. When your car is cooled down, you are ready to work on the cooling system.
  2. Open the hood of your car. Secure the hood with the safety handle. If you have a newer car, you should have a bleeder valve on the front of your radiator. Check in your owner's manual for the location of this valve. If you do start your car, open the valve with wrench and let your car heat up. The excess air will bleed out of your cooling system. Keep your car on long enough to give the (trapped air) time to bleed out of your system.
  3. Let your car cool down. Once the car is cool, take off the radiator cap. Did the level of the radiator fluid go down? If it did, it means you bled the air out of your cooling system. Replace the radiator fluid, turn on the car, and let it run. Replace radiator fluid as needed.

1999 buick century..my temperature guage sometime goes in the red and then back 2 normal...once it does that it takes my car awhile 2 heat up

Hello! Replace the thermostat, it is defective...I would suggest flushing the cooling system with the heat set to high...Your engine requires Dex-Cool anti-freeze...It, due to electrolysis, has a tendency to "clump" blocking proper flow...Drain the cooling system...Fill with plain water...Allow engine to heat up and when the thermostat opens shut down and drain...Do this three times or until water is clear...Replace thermostat and refill with Dex-Cool...Allow all air to escape before installing cap...

86 dodge D100 dies and wont restart

Sounds like vapor lock. In laymans terms the engine heat causes the fuel flow to stop. Once everything cools off the truck starts. Insulating around the fuel line seems to be the solution. Try aluminum foil. Or perhaps a reroute of the fuel line to get it away from direct engine heat.

What I would do is flush brake system could have water in brake fluid. I would also replace both front brake hoses, flush brake system 1st then replace hoses.
