Brake sticking 6340

[alchemist1959]

When I brake in reverse the rear right wheel brake sticks. I usually notice this when I hit wet ground, notice the tractor lugging or smell the fluid burning. I have to release the pressure from the right linkage to fluid cylinder on the rear or the tractor. Where should I look to solve this issue?

not sure if this would apply for tractors but this was a classic indicator of a collapsed brake line in cars. when you press the foot pedal you are generating a great deal of pressure in the system to push the fluid into the slave cylinder, but this cylinder relies on very little back pressure to release. a collapsed line allows fliud into the slave cylinder but the cylinder is unable to push the fluid back passed the crushed part of the line (kinda like a one way valve). as for it only happening in reverse has me a bit stumped. either that or maybe your handbrake is knackered

Most likely RH brake master cylinder pushrod has no free play!

Three good starting points.
1) After 18 years I don't even trust the handbrake.
2) Given my field of operation a crushed line is probable. I have had trees come join me in the cab.
3) A lack of free play on the cylinder is a manual warning.

Time to Sherlock Holmes this thing...
