need Mack midliner brake help

Recommended Posts

Hello, I own a 1986 Mack{Renault} cs200 midliner.. I am having a terrible time locating the part number for the Right Rear{ passenger} brake chamber.. Wondering if anyone has any experience with these things and can provide any info? I called my local Mack dealer and got the usual== snickered at and told to buy a new truck, followed by an astronomical price quote , followed by a refusal to give a part number so I could source elsewhere.... Thanks for any help in advance..

Take old chamber, lay on counter of any heavy truck parts shop and say "One please."

I guarantee it's not a Mack part.

They're probably Renault or Volvo parts.

You can try interweb search for any European Renault parts trader and show them pics of the stuff together with the VIN.

Not shure they will be too likely to dig out an old truck parts lists and than provide send owerseas. But that might be a way if no others.

I use to do such deals on the constant basis although it takes time and a lot of attention.

Thanks for the help thusfar.. more digging today provided that the unit is not a standard 24/24 chamber.. The unit is a lockheed {england} chamber air/hydraulic.. mack part number is [old} =4103 5000 243 790.. NEW Mack number is 8511 5412.. however, these numbers dont correlate to any aftermarket part.. in fact, the numbers dont correlate to anything as a cross reference to lockheed.. Mack has a way of NOT wanting you to be able to easily find parts...

Hard to believe an air over hydraulic brake chamber for a Midliner is over $1,300.00 isn't it? Open the link below to the Euclid catalog and look at page 77. All the parts are listed with Euclid part numbers. Not sure if they are still available since the takeover by Meritor but it's worth a shot.

Locate a dealer for WABCO products. WABCO have made lots of brake chambers for Renault, Mercedes-Benz and other European based truck products.

You've got a really old 200 series full hydraulic with air assist. Ugh. Yes, very few of those left and I can see that one being an issue. I believe it was 86 where they discontinued the full juice brakes.

Yes, very ugly!.... yes, in 1987 they went to full air brakes.. I did locate a chamber on ebay with the help of the Euclid parts diagram{ thanks to that poster} and a lot of phone calls.. I hope the chamber itself is not specific to side though. It seemed like the diagram indicated that only the pedestal assembly was specific for right/left side.. Ihave my fingers crossed because finding one WAS finding a needle in a haystack!
