My brakes need to warm up before working in -10 weather on my 1993 Toyota SR5
So I start to drive and I have no brakes, then after 10 minutes of driving in -10
they kick in. We have flushed the brake fluid and make sure that there is no air
in the line. Now I am pondering is it the brake booster or the master cylinder.
Has anyone had this problem and how did you fix it. I'm all ears.
Had this happen on an old Nash, flushed the fluid re bled the brakes, same thing, if it got below 25 degrees the brakes quit working, long story short replace the master cylinder problem went away. took the old master apart and found water still in the bore even after 2 full flushings, So that's what i ran across.
