Left rear tire is locked up

RagMan56 · Sep 3, 2023

Mitsubishi MT372 and I cannot get the left rear tire to roll; I am trying to tow/move it to work on it. Is there a brake line the needs bled? What else could cause it?

On many tractors the left and right brakes can be activated separately via two separate pedals. There are only brakes on the rear wheels. There is usually a link to tie the two pedals together. It is also possible your differential lock is jammed. Drive is normally on the right wheel and the differential lock adds drive to the left wheel.

No brake lines or dif lock involved. Your tractor should be very similar to many other Asian compacts. Dry, mechanical brakes. The brake units will be just forward of the rear axles. Look under the tractor and you will see a rod connected to a short lever on the outer brake housing. Disconnect that rod from the brake lever. Then see if the lever will move either way and rotate the shaft going into the brake. If that's rusted and seized up the brakes may be bound up keeping the axle and wheel from turning. If needed, that whole brake assembly can be removed for servicing. Remove the six bolts, then overcome the accumulation of rust and crud inside, and it SHOULD come out.

Your were 100% on the linkage call. Took out the connection and the brake swivel was stuck; i had to hammer it to rotate it. Still locked up but progress. This MT 372 hasn't run in two years so I am starting from scratch on getting it rolling. Thanks.
