Changing brake discs and pads

[funkydoodycool]

So this is something I've not done before. Not on a car anyway, and I imagine the concept is much the same as on my mountain bike, just bigger, heavier and.... surprisingly a LOT cheaper.

Anyway, I'm going to attempt to change my front discs and pads (not disconnecting the caliper) tomorrow. Armed with my new torque wrench, Haynes manual, and a selection of sockets and Torqs drivers, is there anything I need to know that I should be especially careful about?

Guys website has a good detailed "step by step" on it

Put something in the caliper to stop the piston sliding out and you'll be fine. You'll probably need a piston spreader as well because the new pads will be thicker than the worn ones .

Yeah thanks, your how to is very detailed Guy! I'll have to find me a piston spreader, it's one thing I dobt have.

i use a g-clamp.
check the reservoir doesn't overflow whilst pushing the piston in.
remember to clean disc & pads with brake/carb cleaner before use

I can't find a piston spreader anywhere....

As for cleaning the discs and pads - is that necessary with Green Stuff pads with their break-in coating?

Found the spreader at the local auto spares shop - £34 but he gave it to me for £30 as a trade price. Nice guy.

Here goes nothing....

OK, that's a job for another day - turns out I don't have all the tools. It was great fun though, jacking the car up and letting it down again once I realised

How far did you get..? IIRC, it doesn't require many tools fwn.

I didn't have a 15mm spanner. But now I have a new set so if we get a nice warm dry day this week, I'll get it done. It's not urgent - my current ones have more life left than I thought.

I am a few days off having the money to buy shorter springs (decided to do that first, to see if I really wanna spend the money on coilovers for this car) so I'll probably aim to do it all at once, as the wheels will be off.

Good thinking, don't forget the 'before and after' pic's .
