Default Cross threaded caliper 😤

Decided to replace my disc's and pads today only to find whoever replaced them previously has cross threaded the caliper 😤. I knew something was wrong when the top one loosened off nicely and the lower one was a b*tch to remove. Anyone got any suggestions on what i can do.

Any good local engineering garage will do it; Timserts are better.

Helicoil/Recoil is a better solution in this application IMHO.

It's quite often normal practice on Aluminium/Magnesium to fit a Helicoil type inserts when the component is brand new. OEM's tend to not do this on items like brake callipers because it's cheaper not to.
When you get the calliper repaired, buy yourself some new bolts, as the old ones tend to have corroded a little. They are available from ICP.

I thought a Timsert was better on a component that would need to be taken on and off over time? Is it not suitable due to corrosion issues?

I'll only use a Timesert or Keensert as a last resort in this sort of app. They are formed from a solid steel which expands at a different rate to the host material and they are often bulkier, removing more of the base material.

They are crap anyway.

Just manually bleed (both sides of the calliper) using slow strokes of the pedal, people rush it pumping away like lunatics.
Start with the furthest away from the master cylinder. Close the bleed nipple at the bottom of the stroke before letting the pedal back up.

I got it sorted all bled and back on the road. I just done the old school 2 man method, the gunson eezibleed definitely doesn't fit though, the impreza doesn't have a regular screw cap thread on the reservoir.

Did you have one of these ?
As Ive used this before a couple of times, before I purchased a proper power bleeder and caps.
Universal bleeding cap
