lawser Posted July 27, 2009 Posted July 27, 2009 Great instructions....Unfortunately i broke the top retaining bolt, anyone know off the top of there heads what size i need to replace ?Following on from that any tips on removing the remainder of the bolt from the arm ? Thanks, Paul Quote
coastline taxis Posted July 28, 2009 Posted July 28, 2009 Go to the dealers for the bolt its only a couple of quid. If there is some of the bolt sticing out of the rear arm then put a nut on it and spot weld it to the bolt, Now tighten the bolt 1/4 a turn and slacken 1/4 turn and just keep working the bolt back and forth till you work it out also keep it well lubricated with wd. If theres none of the bolt sticking out of the arm then youl have to drill whats left of the bolt out starting with a small drill bit and working up in size till the snapped bolt comes out. Or get another rear arm Quote
paul.h Posted July 28, 2009 Posted July 28, 2009 I broke one of the bolts since it cross threaded when putting it back but at first I thought it was tight due to the loctite - this was before I decided the best way was to drill out the loctite once a bolt was out. Anyway, removed the caliper and drilled the bit out of the arm and used a longer bolt to go through the arm with a nut on the back since the threads were damaged in the arm. A big problem was getting a new bolt long enough of the correct tensile strength - the original bolt is 10.8 (stamped on the bolt head) - normal high tensile bolts are only 8.8 and not as strong. In the end I was able to source a 12.9 cap head bolt. From memory the original bolt is 10mm diameter and 150mm long and 1.25 thread - usual bolts are 1.5 thread. The cap head bolt I used was 160mm long, sufficient for a high tensile nut (only 8.8 available) and washer. Until I got the cap head I used high tensile threaded bar with a nut on each end to allow the car to be used for a few days. Quote
