Title: 2000 Marquis Brake Part Numbers
Post by: JimNCheryl Domenoe on March 13, 2018, 09:15:55 PM

Does anyone have part numbers for the brake components (disc, rotor, pads, air cans) for a 2000 Marquis 40' built in April 1999.  I have constant brake problems and I am now in Arizona at a chassis shop and the mechanic is toiling over ensuring that what is on the coach is correct.  Having problems with adequate braking power currently. 

Have had the rotors turned after a lock-up of the front right a couple years back, and a similar but less catastrophic occurrence with the right rear a year or so ago. 

Any help would be appreciated.  It is in the shop as I speak and I figured someone may have the info I need.

If your close to Phoenix or Tucon, Fleet Pride should have all the parts necessary to repair your brakes.

Jim,
Lock-ups are not a common issue on the Meritor ADB brake system, in fact they are very rare. The most common issue is accelerated wear that is caused by improper maintenance (lubrication and adjustment). If your brake calipers have been repeatedly lubed with the wrong grease and not adjusted to purge the excess grease, you may need to disassemble, clean and reseal (not replace) your calipers for them to operate properly.

If your stop-ability issue is a new problem that just started, you should check the air pressure at each brake can to be sure that the ABS system or treadle valve is not malfunctioning, and causing lower than necessary air pressure or retaining air pressure causing the lock -up issue.
