[QUOTE="RossKean, post: 1459692, member: 19880"] Thanks for the follow-up. I'm not convinced that the shared ABS unit was responsible for both front and rear to go out, but I suppose it doesn't matter. If, in fact, they also replaced the right front rotor due to damage, it seems likely that the linked piston pair was also overheated (from application of the rear brake). Although the two piston pairs in the right caliper are not hydraulically connected to each other, cooking the lower would also heat the upper by conduction. If they didn't replace them, keep an eye on brake piston seals and be prepared to change them out if there is any evidence of a leak or if the pads are reluctant to retract when you ease off the brake. I will assume the shop checked them. I also assume they did a full and thorough fluid flush... [/QUOTE]
