Not getting any brake fluid to rear drums to a 1997 Chevy Tahoe
Must bleed air from brake lines. Done so with help of a friend to pump brake pedal a few times and hold while you loosen and immediately retighten the bleeder screw located right where the line enters drum on the back. Use care, as fluid will start to drain out as air is eliminated in line. Do this repeated times. When only fluid escapes you are finished!

Did you clear the code with a Scan Tool after replacing the valves?
The 1998-2001 Chevrolet Tahoe has a known issue with the air pump check valve which causes illumination of the check engine light. There are no notable symptoms, but the vehicle will not pass state inspection or smog testing. When the valve fails, it sticks closed, and the computer sets the code P1416.Dec 10, 2016

How to fix my 2001 Chevy Tahoe tow/haul keeps coming on when not pushed. If I leave it unattended will it cause my transmission problems cause I just had to replace it
Tow/haul mode enables the operator to achieve enhanced shift performance when towing or hauling a load. When tow/haul mode is selected, the tow/haul switch input signal to the body control module (BCM) is momentarily toggled to zero volts. This signals the powertrain control module (PCM) to extend the length of time between upshifts and increase transmission line pressure. Cycling the tow/haul switch again disables tow/haul mode and returns the transmission to a normal shift pattern.
Would't trust it , take an have DTC'S - diagnostic trouble codes checked by a qualified repair shop with a factory or professional scan tool . Auto part stores can not check BCM code's .

I got a 99 tahoe 5.7 vortec with multiple misfires
this is one of those situations that a professional diag would of saved you alot of money. Its possible you just got bad gas and your injectors are partially clogged. An 02 sensor would not give multible misfires. EGR would only misfire at idle if stuck partially open since its suppose to be open cruising. Fuel filter would give you a starvation issue but if the misfires happens at idle then the filter most likley is ok.
Data from a professional data scanner will store the conditions when the misfire occurs. Also for a chevy each cylinder will have a misfire counter and one can see the misfire happening as it happens. If its idling and misfiring and gets better as you rev it up most likely you have clogged injectors or a intake vacuum leak. You can test for a intake leak by spraying the intake area with water(idle will faulter if it draws water in), or use brake cleaner (idle will raise when fluid gets drawn in).
If no leaks are found I would do an injection service or at least add two bottles of techron to a full tank, drve till half a tank then top off again.
Also if the catalytic converter is clogged the backpressure could cause all sorts of misfire issues. Removing the two upfront 02 sensors and driving will indicate the exhaust is clogged or not. We put a pressure sensor in place of the 02 sensor. If the pressure is above 5psi this would indicate some blockage. It should be below 3psi at 2000 rpm. Also if you have K/N filter the oil from it will coat the maf sensor wires in time,, (always). You can remove the sensor and spray the wires with brake cleaner to clean. DO NOT touch them. They can be brittle. Look at the wires for color. They should be shiny silver. If its coated the PCM will not see the air volume or accurately see the air temperature. Without this information the PCM will not add enough fuel which will create a misfire.
Cig lighter fuse keeps blowing out
Research what else is on the circuit. In the old days when cars had more than one cigarret lighter I discovered that a penny fits in the socket perfectly and would cause a short.
