Problems with rear brakes

I have problems with the rear brakes of a Renault 9 Txe Mod 92.
I stayed the right rear wheel and began to smoke, block the circuits that go back from the servo to be able to continue walking because I stop stopped on the route. They told me that it can be the brake limiting valve, can that be?, Any help serves me, and I will need to know if I have to change the brake tapes. Thank you so much.

Good, I don't know if the car you say carries drums behind, which is the most caused, so it can be from Mobmim, of the same shoes that have been blocked by the tensioner, or by the braking regulator. The drum disseminates and looks at the site of shoes and mobines, if this corresto is, it will be the regulator, which goes in the torsion bar, which has been fucking.
Anyway, look at the handbrake cables, to see if anyone has been seized.

Hi Rubén, thank you for answering, look at the handbrake cables are both well, tomorrow I will check what you told me and then I tell you, thank you very much.
Greetings.

Hello.

Verify pipes and flexible rear brakes. When a pipe is obstructed or a flexible is deforming wheel blockages ... Rear braking compensator could be more likely in case both wheels are blocking, verifies rear braking regulation before all. greetings
