My bus uses type 24 rotochambers on the front axle. I would like to convert both sides to standard brake chambers as a single rotochamber is $500 and hard to find. My problem is the type 24 rotochamber is 6 13/32 inches diameter per Bendix (matches my measurement) and a type 24 standard brake chamber is 7 7/32" per Bendix. (I already had the tag axle converted to standard brake chambers.)
It does not appear I have an extra inch of clearance so any suggestions other than just buying another rotochamber? I assume I'll lose too much braking performance going to a type 20 or tpye 16 brake chamber.
Does your slack adjuster have a second hole closer to the S-cam, that would give you more leverage? Do you have a half inch of clearance (you need a little less than an inch of diameter, so under a half inch on radius).

One of the c models from MGM should work fine,you will never notice any difference in stopping going from a 24 to a 20 on the front axle the H-45 Prevost a lot larger bus than your Dina has 16 service chambers for the ABS system I Installed 20's on the Casinos bus it hasn't killed anybody yet
I need to look a little closer to see if there is enough clearance. When I was out there today I just measured the rotochamber. I had a brake issue last fall and the bus garage I went to pulled out a type 24 chamber and said it wouldn't fit due to diameter. They thought the chamber was bad, but it turns out clevis pin was seized. I want to replace chambers to prevent future issues.
It is fairly common on the Dina buses to convert from rotochambers to standard chambers due to cost. I had asked BK about his Dina some time back, but the conversion hadn't been done by him. It sounds like a type 16 will work if something larger won't work. I'll also look at the MGM product.
Thanks for the help everyone.
