SOURCE: changing 4 calipers and there is no oil com out when try to bleed

The master cylinder supplies the pressure to the brake fluid that travels between the maste brake cylinder resevoir and the brake caliper pistons (through the brake lines. If the master cylinder fails there will be insufficient compression of the brake fluid to make the calipers operate as designed. Leaks in the brake lines and/or cylinders is a possibility, and unrelated to functionality of the master cylinder. Also, pistons located in the brake calipers can form a corrosion ring on their inside walls if there is breakdown in the brake fluid or moisture that gets into the lines. Operating the vehicle when there is insufficient brake fluid in the master cylinder resevoir can also lead to air getting into the brake lines, causing bad working brakes. Air compresses more than brake fluid, and the master cylinder isn't designed to compress air in the brake lines. Sounds like a bad case of "lack of maintenance", as opposed to bad advice from the mechanics. That said, there's no excuse for bad installation. But, it's tough to improperly install a brake line since they are nothing more than hollow metal tubes. There should be no rubber connectors installed in the brake lines. When bleeding the brake lines one must remove all of the trapped air before you will see any fluid appear. If the valves in the master cylinder are not properly operating the master cylinder will not allow the brake fluid to get into the brake lines.

Hope this helps.

SOURCE: 1998 Chevy Lumina 3.1 overheating - top radiator hose collapses on throttle, then opens up when you let off.

With the engine cold remove the radiator cap. Start the engine. Watch the coolant. If you see bubbles constantly perkulating out of the coolant than you most likely have a head gasket that has failed. If you don't see a constant perkulation of air bubbles it probably wouldn't hurt to replace the upper hose and see if the problem is resolved.

SOURCE: what cause a vacuum hose on the driver side of the engine to collapse

The hose that collapses is weak and needs replacing. The engine vacuum cannot be all that great, normally runs around 17-22psi at idle and only increases a little during deceleration, not above about 26-28psi. Not enough to collapse a good vacuum hose.

I have a 1986 Chevy Silverado with a 350 engine, why does my top radiator hose keep collapsing?

The hose collapses because there is air in the cooling system. If the system is properly full, the hose cannot collapse because water does not compress. If there is a leak in the system, you need to repair it, refill and bleed the cooling system, and ensure that the reservoir has a proper level of coolant in it. If there are no leaks in the system, then the reservoir (recovery) bottle could be low on coolant, allowing air into the system during the expansion and contraction that occurs as the coolant heats and cools. Another thing that can cause this issue is a defective/worn out radiator cap. I would recommend replacement of the cap, refill and bleed the cooling system, then top off the reservoir and then monitor for any further issues.

Having trouble with drivers side rear brake....once brakes are replaced about 2 months later the drivers rear brake starts to grab and squeal like a train stopping keep having to mechanic and...

yes, because the master cylinder should let out equal pressure to both the back breaks. somthing might be causing the break to clamp harder than the other.

A collapsed hose will restrict (or completely block) water flow, causing a overheating condition. Before you do anything else, replace the hose. Some aftermarket hoses are available with a wound steel coil that will prevent a hose from collapsing.

Good time to replace all the hoses and thermostat. If I were you, I'd also flush the cooling system while I was at it. Probably wouldn't be a bad idea to take a look at your serpentine (or "v") belt to.

If your particular vehicle has air bleed ports, be sure to properly bleed all air from the system when refilling with coolant. Usually the bleed ports will at or near the point of attachment of both the upper and lower radiator hoses to the engine block.

Good luck!

My oil filter is collapsing after about 1000 miles after the oil change.

You are probably buying cheap filters. Fram is not your friend. Get something of good quality. It's also possible you're not seating the filter correctly during installation and it's collapsing from improper flow.
