I want to get the correct tool to remove the brake wheel cylinder from my 95 Blazer and I am unsure of the correct size and whether it is metric or SAE.

Thanks for any help,

I currently have a bottle of brake fluid, oil pan, socket set and I can get the brake wheel cylinder at the Auto store across from me.

 

Metric.
You're going to need brake tools also

Do you have some syl-glide for the backing plate and pins? You want to lube the pivot points.

 

It's been a while since I did mine... I want to say you'd need a 13mm wrench or socket, but don't quote me on that.

 

Just replaced the rear calipers on mine (USA). 13 mm for two caliper bolts, 10 mm for the bleeder.

 

just speaking from experience dont use a regular wrench get a set of "box wrenches" you will be glad you did not so much for the bolts that secure it to backing plate but the actual brake line. you dont wanna round that off. spray it with PB blaster several times then let it sit overnight. makes life easier

 

He has drum brakes in the rear.

 

I stand corrected and informed. My apologies.
