Progress report:-
Well,I've actually managed to get one bolt out now - the easier bottom one. I found a 6 point 13mm socket in my 1/4" drive set but the 1/4" extension bar was too springy and wouldn't do anything. Luckily I had adapters to step it up to 3/8" and again to 1/2" to allow me to use a long 1/2" extension bar which I could then access from under the car. I supported the ratchet end of the bar with a scissor jack but even with the 1/2" ratchet it wouldn't budge. Finally I used my torque wrench which is 30cms long and that did the trick. Access to the top bolt is very limited and before I lash out on a set of Irwins, I'm just going to try a 13mm 6 point ring spanner which hopefully will turn up soon. |

I hope the bolt undid within the limit of your torque wrench setting or you can ruin the calibration. While others may, I would never use a torque wrench as a socket wrench for undoing nuts or bolts, it is a "precision" tool macafee2 |

You're quite right. It happened to be set at 90 Lbs-ft and didn't click. Malc Last edited by chicochapman; 29th April 2020 at 09:04.. Reason: Corrrected the units of torque. |

Malc you need the correct tools for the job mate - a decent 1/2 inch drive set for these bolts. Using 1/4 drive with adapters risks them snapping and you don't want that happening when you a have all your weight on it.
And as Ian said, torque wrenches should only be used to tighten nuts and bolts - they only go both ways so that you can tighten left hand threads. |

Mike, you're right but at the moment, I'm having to improvise with the tools I've got. I couldn't find my 1/2" 13mm socket which was why I used the step up combination but plus points for Draper Tools as their small socket held firm. I have 1/4", 3/8" and 1/2" socket sets and various ring spanners.
Having later found the 13mm 1/2" socket, it will fit, but there's no space to fit any thing to drive it with ( even with a universal joint) plus 13mm and 1/2" ring spanners are slipping. I've put the torque wrench back in its protective tube! Malc |

Easiest way order 4 new bolts.
Then soak in plusgas and remove with 13mm IRWIN extractor bolt using a 19mm open ended spanner on bolt extractor.......... Job done. |

I'm a great believer in Plus Gas myself but in this instance I don't think it helps too much as the mounting bolt passes through the caliper carrier and only screws into the trailing arm. On the bolt I removed, you can see only the last section of the shank has screwed in and the Plus Gas might not reach that far.
(bit of camera distortion there) Anyway, I can see that Irwins are the ultimate answer but I'll give the 6 point ring spanner a go when it turns up - hope fully Friday. As an aside, I've had EBay parts in the postal system for 15 days before they turned up. Still, plenty of time at the moment ! |

In all honesty the Irwin bolt extractors are a god send, I would highly recommend in investing in a set,you will not regret it.
If you do remember to use a 19mm spanner on the extractor as opposed to a ratchet. All the best |

Their sets or at least the ones I have seen combine imperial and metric extractors. I would think for our cars a pure metric set would be better. When Irwin have worked, I totally agree, a god send. I just ask, is there a better set? macafee2 |
