Del Gue Posted October 24, 2011 Share Posted October 24, 2011 I recently put in new rear brake kits on my 99 OBS. It has drums. Do the brakes automatically adjust while in reverse, or do you manually set them? Of course there are adjusters in there, but I'm not sure of the process for adjusting them. Fuel injectors. My vehicle has 80,000 on it. When should fuel injectors be replaced; how difficult is the job and what are the expected benefits of new ones? Thanks for all the help.

Rooster2 Posted October 24, 2011 Share Posted October 24, 2011 (edited) No need to replace the fuel injectors, for maintenance, just add some fuel injector cleaner like Techron to your fuel tan. Cost about $5 to $6 per plastic bottle. Don't bother with cheap injector cleaners that cost $2 to $3/bottle, they don't work well.
