I cooked the passenger brake caliper on friday. Fried the brake hose, and hopefully NOT the unit bearing. Clear coat on the wheel has bubbled, tire looks a bit dull. Holy brake barbecue Batman.
Waiting for my parts now.
Here's the situation.
installed this year- may 2008
new MC
Booster
wheel cyls shoes
new axle hard lines
Castrol Dot 3/4 LMA brake fluid
installed Oct 2006
Crown Performance brake lines
Here are the possibilities before I tear it down.
It's possible a Crown brake line has collapsed internally, and caused caliper seizure. There is no outer sign of collapse, no leak or kink. Just a 2 year lifespan for a mostly street driven brake hose. Pathetic.
Switching from Dot3 to Castrol LMA Dot 3/4 may have caused the old phenolic pistons to sieze because they swell slightly. Got metal piston calipers on order.
Old-ass caliper finally got hot enough to get snagged up in the bore. Being worn out can cause them to seize too.
Steering knuckle ridges? Havent seen how bad they are yet. I'm ready to grind them bitches already.
The incident started with a bang, which I believe was the caliper piston breaking free from sticking, for the last time. After that the jeep pulled more and more to the right, and then to the left on braking. I ditched at Northen Tool, and voila the caliper was smoldering.
conclusion- Stainless braided brake lines may have short lives, and go suddenly. We'll see if that's the cause after I finish pulling parts.
I'm going with metal pistons this time...and rubber brake hoses.
