Working on a 37 chevrolet with updated suspension but can't seem to come up with what it is Narrowed the brakes down to very early Mazda/Ford Courier pickups Brake parts are Akebono 9 inch rotors found some calipers (we think) but no 9 inch rotors only 10 inch See pictures maybe someone will recognize Car was built probably in the 80s Any help Thanks in advance Here are some additional pictures of the front suspension This suspension has shocks and the lower ball joint has one thru bolt and a single bolt for stability see image View attachment 6371150 View attachment 6371151 View attachment 6371150 View attachment 6371151 View attachment 6371152
wonder why rockauto only shows drum brake parts for the early Courier? wouldn't hurt to get some better pictures, showing the whole front suspension....just in case someone might recognize it. Just stand back a foot or two further, when taking the pictures.
Ford Courier '72-'85 (mini truck) = Mazda b series, disc brakes were available in later years. I believe those were all 6 x 5.5 bolt pattern also, but I recall a funky disc with a 'hat' that could probably be re-drilled to a different pattern.
Here is a picture of the disc and hat bolt pattern is 4-1/2x5 The disc is 9 inch but can't only find 10 inch
did you remove a few pictures of the calipers? where it had letters/numbers The other pictures are great, unfortunately can't find anything like that lower ball joint anywhere
That adapter hat thing on the disc is what I recall, except in 6 bolt, from some brake jobs back in the '80s on a Mazda B. But that was a LONG time ago! Here's a pic of a '73 Courier from a Bring A Trailer ad - similar-ish but not the same:
Highly suggest measuring those rotors in all dimensions. Diameter, thickness, height, registrr bore and bolt circle. Metric will give you accurate numbers. Hub over rotor design is more common from the import market. Datsun/Nissan was a fanboi of this design. For a 9" solid rotor, if it is a front HOR type, maybe look at Toyota Tercels. Otherwise if the rotor is a 9" version of the 10" Mazda Courier, dimensionally, might be easier to simply have the 10" rotor machined down to 9". With the solid rotor I would not be worried about balance issues that a vented rotor may have. Albeit that front brake setup clears drum type rims. Would be a shame to not utilize that feature.
Very similar on the cross member for sure The lower ball joint that are on mine appears to be like these which are for a mazda hilux has a 3 bolt ball joint
Thanks to everyone that have given their input on this suspension and brake issue Still on the search for the a-arm manufacture and the brakes,have considered possible trying to get an updated conversion for the front Second want to get everyone's input on the brake hydraulic system on this car It appears that the master cylinder may be undersized for this car and that there isn't a proportional valve in the system master cylinder is plumbed directly to the cylinder on the vacuum booster then a tee to front and rear brakes disc on front Drum on the rear Customer wants to install 4 wheel disc Thoughts Thanks in Advance wayne
That single reservoir master cylinder may not be able to provide enough brake fluid volume to operate 4 wheel disc brakes, but that will depend on the size of the 4 disc brake calipers used in the system. Once the brake system you intend to use is identified, the master cylinder can be determined by the needs of the brake system installed. Does the current system use a mater cylinder to activate a remote master cylinder with a booster on it and that master cylinder activates the brakes? Looks pretty strange to me.
To answer your question yes the single master cylinder goes directly to the cylinder on the booster without Proportional valve then to all 4 wheels The system looks weak to me also I have read that some are not using any sort of power assist but rather a corvette style master cylinder with a 1 inch piston without any problems The rear conversion will be for a 1970 Camaro Rear axle the front is still in planning stage
That combination of fruit jar master cylinder and remote booster was commonly sold by streetrod dealers in the 1970's before the dual master cylinder and smaller boosters were fazed in. That booster was factory on 1957 TBird.
