[TR] TR6 Brakes

[davehogye]

Yes, absolutely. New ones are available for around $80 a piece. The rubber lines are also a common problem. They collapse or swell internally. If you crack the line open along the way from the caliper towards the master, the cause of your problem will be evident. 
When a car sits for any length of time, I would always replace all hydraulic components. Always. Brake components are inexpensive insurance and more important than forward motion. If any component is leaking, corrosion is most likely the culprit. There is no good reason for rebuilding, just replace everything. Start with a clean slate. You will not regret it. If a wheel cylinder is leaking then the rest of the system is suspect too, if the car has been sitting for any length of time. If a caliper is frozen, then definitely replace all components. Cheap insurance.

Dave, 

It is possible the calipers are corroded and froze. The car has set for a while and I live in northeast North Carolina where we have humidity issues. Thanks for the suggestions.

Calipers are seized from corrosion or flexible rubber lines have collapsed internally.

Hello Everyone. 

I finally had a chance to take the TR6 out last Sunday. I had an issue with the brakes. The front brakes locked up. Each time I applied the brake they just locked up tighter. I haven’t had much of a chance to trouble shoot the problem but it appears that the brake fluid is not returning back into the reservoir. I did crack the line at the master cylinder for the front and the pressure differential valve. Some fluid started to come out of each one but I closed them both quickly after a few drops. Didn’t make a difference, could be because I didn’t let enough out. 

Before I tear the entire system down any suggestions as to what the problem could be? This might be an opportunity to rebuild the system and replace the fluid with silicone and rebuild everything.
