Hi All. Its been a while. I have a 10 year old TiLite TRA-Had D's put on the day it was built and all was fine- about almost a year ago I replaced them but they locked up again this evening-fell apart while I was pushing home and locked in place blocks from my house- ugly( called friends etc ) before I replace them with another set of D's again what are the best other options- I put the hand brakes that came with the chair though when pushing my hand will run into the brake if I do not my hand and as a result its short push rev cycles if that makes sense.... Thanks in advance- I hope you all are well and had a fulfilling Thanksgiving Day!! Daniel
