Question about 2005 Chrysler Town & Country
The rear brakes lock up and tend to skid, especially the right rear. the entire system has been replaced,drums.shoes, backing plates.etc. stopping distance as increased . slow (long) applications do ok, but quick application of the brakes makes the ABS work thus the tires feel like they are jumping Drove van into garage as usual when trying to back the car out the following week, the back brakes were locked. Did not apply the brakes hard when parking the car in the garage. I did drive through some water when entering the driveway. Brake fluid was checked and is okay. Any thoughts.
ABS hydraulics on that unit are a known problem.
The dealer has a set of gauges to install and verify.
Shop around for prices on one, including salvage, then take it to the dealer to verify the concern before you shell out a couple hundred bucks.
Its not a tough replacement if you are handy with a wrench.
If not, leave that one to the pros.

SOURCE: rear brakes lock up
Not wanting to be too general but at least trying to help I would suggest
looking under the back end, and specifically at the rear backing plates
and to the insides of the rear wheels, to see if you notice any fluids
dripping. If these are drum brakes, then you could very well have either
a wheel cylinder leaking brake fluid, causing the brake shoe linings to swell
up, or it could be a leaking axle seal, allowing differential gear lube out,
which will also cause the linings to swell, and minor braking will cause
that particular side to lock up.
If this vehicle has rear disk brakes, or was just recently changed from rear drum brakes to rear disk brakes, it is possible that the proportioning valve in the brake line was not changed to match with the disk setup.
Drum brakes operate at approximately ten pounds per square inch pressure (10 PSI) whereas disk units operate at a lower pressure of about 2 PSI.
Just some things to look at. Some brake fluids have no smell, others are very distinctive in odor, and differential gear lube has a very distinct odor...not hard to miss once you've smelled it.

REMOVAL & INSTALLATION
It is a good idea to only disassemble and assemble one side at a time, leaving the other side intact as a reference.
The drum brakes are self-adjusting and require a manual adjustment only after the brake shoes have been replaced, or when the length of the adjusting screw has been changed while performing some other service operation.
Fig. Fig. 2: When using a brake adjustment gauge, first measure the inside diameter of the drum (top) and then adjust the brakes shoes to the proper outside diameter (bottom)
Fig. Fig. 3: Measure brake shoe thickness in several places around the shoe
Inspect the brake shoes for wear using a ruler or Vernier caliper. Compare measurements to the brake specifications chart. If the lining is thinner than specification or there is evidence of the lining being contaminated by brake fluid or oil, replace all brake pad assemblies (a complete axle set).
