Imperial Brake System Part Numbers

Imperial Home Page -> Parts -> Brakes -> Part Numbers

Read the 1953 - 1961 Chrysler parts manual which includes numbers for the brake systems on these models.

BRAKE SHOES - DISC PADS

Shoes

NOTE: On many, if not all, master and wheel cylinders and calipers the casting number can be used to identify the correct part. Unfortunately this does not guarantee availability, especially on some of the early disc brake calipers. Ask if the parts source has a casting number interchange or buyers guide.

For drums and rotors, in general they are getting harder and harder to find. It has been recommended that checking and replacing the shoes or pads before they wear into the drum or rotor will help prolong the service of the drums and rotors. In any case, it appears that NOS and used parts are about all that's available. Some IML members have had luck in using other brand drums and machining the centers to fit the axles. This is an individual decision taken at your own risk.

NOTES ABOUT THESE PART NUMBERS: Due to the fact that Chrysler no longer produces many of these parts and that Chrysler part numbers are quite often superseded or not in the Chrysler parts system any longer, aftermarket numbers are used. If enough current and correct Chrysler numbers are available, they can be added for what is still available from Chrysler.

I have arbitrarily chosen NAPA parts for the aftermarket, simply because of the availability of NAPA outlets and the fact that I have previously worked in their parts system. This IS NOT an expressed or implied advertisement or endorsement to use these products. MOST PARTS OUTLETS CAN INTERCHANGE THESE NUMBERS IF YOU DO NOT HAVE A LOCAL NAPA OR PREFER NOT TO PURCHASE FROM THEM.

IMPORTANT: ALL THESE REFERENCES HAVE BEEN ONLY SEARCHED FOR IMPERIAL OR NYB AS APPLICABLE. WHEN RESEARCHING THESE PART NUMBERS I SEARCHED FOR IMPERIAL, MODEL YEAR, ENGINE SIZE AND ANY OTHER NECESSARY DATA PERTINENT FOR THAT PARTICULAR PART.

FOR EACH GROUP OF PARTS THE SOURCE AND BRAND WILL BE LISTED< AS WELL AS ANY IMPORTANCE OF THE PART NUMBERS USED. IN THE CASE OF REBUILDABLE PARTS OR PARTS NOT EXPRESSLY NAPA- NOTES WILL INDICATE THE USE OF SUCH NUMBERS AND SOURCE.

Now when some uninterested, uncaring and uninformed counterman says " they didn't make that in that year......" or " its not listed...." you will have the upper-hand.

NOTES ON REBUILDABLE PARTS:  Many times a part is not available because the rebuilder has no "cores" from which to remanufacture a part from. It is usually possible and sometimes cheaper to send your part in - if you can be without the vehicle for the time required. Most of these parts are rebuilt by major suppliers to parts stores, regardless of the individual outlet. ( It is not uncommon for competing retail stores to be supplied by the same rebuilder) Some parts require the services of smaller specialized rebuilders, especially for vintage or very rare applications...

The following is a non inclusive list of many of the parts that can be easily rebuilt today:
Alternators, Generators, Starters, Water Pumps, Power Brake Boosters, Carburetors, Distributors, Brake Shoes, Master and Wheel Cylinders, Brake Calipers, Air Conditioning Compressors, Power Window Motors, Convertible Top Motors and Cylinders, Power Steering Pumps and Gearboxes, Wiper Motors, Motor and Trans Mounts., Fuel Pumps, Harmonic Balancers, Driveline Supports, Clutches and of course - Engines and Transmissions.

So if all else has failed, find a local or larger scale rebuilder either on your own or thru a parts store. DON'T SCRAP THE PART - if you have patience you can usually find someone to help.
