Tech Question
Justin Trusz, Watson Lake, YT, Canada, 71 Chrysler Newport SE 440
Hello Rick,
Me again from up north. Just a quick question for you --
I read in a Mopar mag, not sure which one, that pre-1972 Chrysler disc brakes had a tendancy to come apart at the hub, something about these being pressed together units. My newport is a 10-71, 'bout as big and heavy as they ever got with her being a four door (YES I know the whole thing of four doors not being collectible, too bad, she's my first true musclecar in MY mind!), and I REALLY would rather not have to worry about the power discs up front coming apart at an inopportune time, especially since both discs are still in top (for a 71) condition. Is this a valid concern or a puff of smoke?
Thanx muchly, you guys can expect a subscription from me shortly. Keep the Mopars Rippin'.
Justin-
Either you're memory is faded, or you read some misinformation elsewhere, which, with the dubious quality of what passes for "tech" in some so-called Mopar-like publications, is entirely possible.
The problem you're referring to occurs on on early unicast rotors - the one-pc. units that were made without reinforcing ribs in the hub area, from 1973 to about 1978. Cop cars always had the ribs, as have virtually all replacements, OEM Mopar and aftemarket, since approx. 1980.
Your two-pc. rotors are immune to this. Your hub is a beefy forging! The rotor is held to the hub by the studs and wheel lug torque (you DO torque the lugs to 85 ft./lbs. in a star patter, right?) Relax!
Rick
