Please fill out the following to ask a question. MAKE: jeep MODEL: Cherokee ZJ YEAR: 1996 MILES: 152ooo ENGINE: 6 cyl DESCRIBE ISSUE....Rear disk brakes calapers are not releasing. Both rear wheels are sticking. Both rear wheels are restricted and get very hot. Vehicle can not be driven. I have disconnected the brake line from both rear calapers hoses . With this done I can compress the piston of both calapers, meaning calapers are ok. I opened brake line on the frame rail at the brake hose to rear axle and have a restriction between these 2 points. There is a splitter mounted on the axle shaft. The input hose goes into it 2 brake lines leave it. and there is a hose leaves it from the top . What is the purpose of this hose and where does it go? The splitter looks to be permanent mounted to the axle shaft. How do I remove it if I have to replace? The restriction is in the splitter or the hose feeding it. If anyone has had this problem with a jeep Cherokee please tell me about it. and trll me the purpose of the tube in the top of the splitter.
