Hello to all.
I have 2002 Envoy Slt (236000KM)and i have replaced the front rotors and callipers and run into a problem with the drivers side calliper. The issue here is the calliper was a remanufactured one and a Heli coil was used for the thread on the hose to calliper connection and it failed( or I helped it)
The connection was never good and I was getting brake fluid seeping, in an effort to stop the leak i (honestly) gingerly tighten the bolt to torgue specs which resulted in the bolt just being loose with more loss of fluid. I am now faced with the task of redoing the heli coil, which will have to be bigger because the hole in the calliper has no more threads and they will have to be re-tapped. Has anyone used other products other than heli coil for this problem and could they share what they have learnt?
Where do you get the copper washers for the brake lines, the washers that came with the callipers are very thick by comparison and are not copper. The dealer does not have them or even sell them. These washers kind of remind me of the washers that are used on the banjo bolts for the Volvo turbos.....maybe that is a source!
Lastly, I had decided to put the bigger rotors and matching callipers on the fronts, was this a mistake, should i have stayed with the standard rotor and calliper size for this model . There does not appear to be any ill effects in the fitting , except for the little overlap of the rotor when compared to the dust shield, where the rotor is 1/4 " ( about) larger than the dust shield.

go to the junk yard, get a caliper cheap. I would not trust a helicoil to fully seal, and am very surprised someone would sell a reman'ed caliper that had to be "repaired" like that!
