Miata Front Brakes

Time to replace the front calipers, had to replace the rear calipers last year as they were leaking at the parking brake lever seal.


I decided to do the work while still loaded on the trailer for
better ergonomics


















Forgot to paint the calipers so I have to
wait for paint to dry...  (also when trying to free a stuck brake piston one can
push fairly hard with loose C clamp to use the hydraulics to free it but once the piston
moves do not pump the pedal one more time just a bit harder...)



Pressure brake bleeder system will make the bleeding process
far easier

A POX on AutoZone - they gave me the wrong rotors (Then again I should have checked...)
so I had time for the paint to dry as I made a trip to town for the correct ones.

All done and bled - ready for the wheels.  Using a lug nut to hold a wobbly rotor
is a handy trick when trying to bolt the caliper bracket back on.  Also install the new brake
line last so you do not need to worry about stressing the hose.  (I do not like the Miata front
hoses - too short to turn the wheel to full lock when the suspension is unloaded - I thought
I got the wrong parts but I checked old to new side by side and they were the same length.) 

Last brake job of the day - replace the rear brake proportioning valve - much easier to get to
than the pair on the 1800ES - nice Subaru part supplier pointed out I only needed one for
this vehicle - the 1800ES needs two for the dual split circuit braking system on pre-ABS
Volvo's with 4 wheel disk brakes.
