Front Brake caliper

[Stevie35]

So how do you get your front pistin back in andy? G-clamp? Use the wind back tool with a double depth in they are torx screws not phillps head

You just squeeze the piston on front calipers. If I'm changing discs and pads just use a flat head screwdriver, once the brake fluid cap is off just use the old pads against the old disc to squeeze the piston all the way back before dis-assembling the calipers.

Pffft just as as easy to do it my way

Don't forget to remove some fluid (if it's been topped up over time). You should be ok if the level of the fluid has gone down with the pads wearing. I was ok when I did mine.

Genuinely never had this issue neither have i had to remove reserviour cap if i'm doing it wrong then stupid me but i understand the theory

If you don't remove the reservoir cap you can build pressure in the system which could result in popping a few seals in the calipers it's a closed system and your trying to compress it that's why you take of the cap to help relieve the pressure.

Also some garages where mechanics have become zombie technicians no longer have the brain cells to check weather low brake fluid means a pad change so when they see the fluid low they just top it up then when u go to change the pads u have excess fluid in the system which if not removed will just spill out.

Hmmm can't say ever removed the cap either. I thought the pressure would find it's way back to the reservoir tank in the engine rising the level?

You say pop a seal how would you know?

[Mattyj]

My arguement to that is your letting air into a sesled system by your reackoning

Well if you pop a seal on you caliper you brakes won't work and you will have brake fluid coming out the dust cover

Also as for letting air into the system your not letting any air in your just allowing a non pressurised path for the fluid to return back to the reservoir.

Everyone may not do it like this but that's how I was shown to do it properly, by a mechanic

Here is a guide from another forum saying to open reservoir cap before pushing front or rear calipers back.

This doesn't prove your point its just someone else who agrees with yo
