changing front brake pads on my 10 plate Jimny. was created by Shipjohn
What do I need to do to change the front brake pads. I may need to skim the disks so they would need removing. Any advice would be most welcome. Thanks. I do like my Jimny!.

To just do pads then you take the wheel off and then there are 2 12mm bolts that hold the caliper sliders on. The sliders will almost certainly be seized nearly solid unless they have been off in the last year. To get the discs off you need to remove the 2 17mm bolts for the caliper carrier. Don't let the caliper hang by the brake line flexible pipe use a bungee or something to support it out of the way. The discs are also likely to be seized on the hubs too. If budget allows for new discs you can beat the old ones off. If the budget won't allow replacement then a soft face hammer or similar will save some damage.

You'll also need to push the piston back in using a big G-clamp and a block of wood, or similar. If the brake fluid has been topped up to the MAX mark then you'll need to suck some out or open the caliper bleed screw while retracting the piston.
You MUST thoroughly clean the hub face before fitting new discs or refitting skimmed ones. Ideally you should also get a dial gauge and check runout before using the car. If the discs are fitted to a dirty hub and have more than a gnat's whisker of runout (0.05mm is a common limit) they will need doing again in 3,000 miles' time. I'm afraid some professional mechanics fall prey to this one.
If at any point you're not sure what you're doing, get someone who does. Front brakes in particular must work!

It scares me whenever I see people asking on the internet how to work on brakes...
Please don't beat on the disks with a hammer, it's designed with "jacking screws".

Thanks Lambert for your help and concern, I am a retired agricultural engineer so I understand the safety issues, it was just what process I needed to adopt, I will try and fit new discs as well. Thank you for your concern. John.

Definitely do not open the bleed nipple
Remove the cap on the reservoir this will allow fluid to be pushed back
Just keep an eye on the level
