Daveinbuffalo Posted January 23, 2017 Share Posted January 23, 2017 HELP...I have a 2003 CH613. When I brake, it pulls hard to the left. Help. I have replaced both front shoes, cams, bushings, slacks, Alignment is good...tires are good... we are at wits end....any help would be great. Thx in advance. Could it be the foot valve?

fxfymn Posted January 23, 2017 Share Posted January 23, 2017 I'd check to see if air is getting to the right wheel since you replaced all of the brake parts. A pressure gauge attached to the end of the line may tell you the story. Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

fjh Posted February 8, 2017 Share Posted February 8, 2017 (edited) check to see if air is getting to the RIGHT side! Plugged hose bla bla !Its likely not the foot valve!

Underdog Posted February 8, 2017 Share Posted February 8, 2017 I recently pulled the wheels on my MH... One wheel brake lining looked brand new compared to the others. That particular brake was not even working. Turned out to be a seized slack adjuster.

Our new freightliners the brake cams are sealed and nongreaseable. We have had several that the front cams are rusting fast.

That makes no sense... A moving part with no grease fitting. Reminds me of the Ford pickup trucks with "no maintenance" front ends. Yet all the aftermarket replacement parts had grease fittings lol 1 Quote Link to comment https://www.bigmacktrucks.com/topic/48489-2003-mack-ch613/#findComment-361474 Share on other sites More sharing options...
Hobert62 Posted February 12, 2017 Share Posted February 12, 2017 The tubes are drilled and tapped with a plug and warning lable that says removal will void warranty. The cams get so tight it takes some heat and a BFH to get them out. They are warranty though. Just like sealed dolly wheel legs. They drill them to put grease zerks, sure it voids warranty but its nice to be able to turn them.

Told me yes, freightliner is just as you describe, Robert. But as soon as warranty is out, they install grease fittings.

j hancock Posted February 13, 2017 Share Posted February 13, 2017 Grease is CHEAP! Grease fittings are CHEAP! Being able to properly service a vehicle is priceless. I better sit down now.... 1 Quote JimIt doesn't cost anything to pay attention.

Idk if they where supposed to or not but its better not to question some things. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/48489-2003-mack-ch613/#findComment-361573 Share on other sites More sharing options...
