Like the honda on the movie baby boy the wheels stick out on the side
You didn't state the model or year or the type of rear brake (drum or disk), so I'll be rather general. From your description, I'm guessing you have drum brakes on the rear axle. Before doing anything, try this: start in reverse instead of ahead - is it any easier? If yes, the wear-recovery device sticks. In either case, the rear brake mechanism (or calipers) should be dismantled, checked fo wear (likely premature wear of pads due to seizing), cleaned and reinstalled. Check that the springs (on drum brakes) are correctly installed, that the drum/disk surfaces are evenly worn and that the pistons move freely along their entire travel. Check also the state of the seals and replace if necessary (worn/broken seals lead to pistons rusting and sticking). This is a good moment to do some bleeding as you'll have released the bleeding valves to move the pistons. Next, check the parking brake cable, linkage and levers - they, amay also cause or contribute to the problem. Not using the parking brake increases the sticking effect. If the car is old, replacing the cable is the best strategy. It should never be lubricated. On disk brakes, caliper and pad guide metal surfaces may be slightly lubricated with hi-temp (copper) grease. Keep it well away from the friction surfaces and disks. I can hardly believe the garage has gone this far. Btw, unless you regularly park in knee-high water or your car has been flooded, I can't imagine such a dirt buildup to justify the effect. Your best bet is a friend with some time, tools, experience and a place to do the job. It shoudn't take more than half a day to do most of the work (time to procure parts excluded).
Wheel spacers is the cheapest way to go. You can find them on eBay pretty cheap. To get them to stick out as far as they did in the movie you'll need to order rims with a positive offset. Any good rim dealer can further explain it to you. Just so you know positive offset causes wheel bearings to fail fast. Usually every 15,000 miles or so depending on vehicle weight and driving habits.
Install a set of wheels with a different offset. Offset is the distance from where the wheel mounts to the hub to the center of the wheel, so you can move wheels in or out by buying wheels with a different offset number. And keep in mind that trying to get this look by changing wheels will be murder on your wheel bearings and can have annoying effects on the handling. The suspension is not designed for moving the wheels outward four inches. I've heard accounts of people who had to replace their wheel bearings every two or three months. If you wanted to move the wheels out with no bad effects on your suspension's reliability or handing, you would pretty much need to give the suspension a complete redesign.
