Brake Lines Blown While Towing with Toyota Tundra!!!!

Thanks for the replies. To answer your questions...my trailer is 5k pounds dry. My brake controller is a tekonsha prodigy proportional brake controller. When i say the brake line blew i mean it sprung a leakjust above the rear diff. The dealer said it was squirting brake fluid whenever you apply the brakes. His initial assessment was that he could see no signs of physical damage.

I will wait to see the final report.

No vehicle mods.
