Just a quick note to ask how different a 4x4 ABS front pad replacement is. I've never done those before and when we pulled off the front tire I saw two large bolts (with what appeared to be a spring) running from the inside to the outside holding on the calipers...it is prtetty much straight forward like a non-4x4? Any help would be nice thanks
the best thing you can do is get a haynes manual. i did the brakes on 3 vehicles so far w/little experience (i've only been driving for a few years). the haynes manual will show you every step and also tell you what parts to lubricate. the amount of money you save doing it yourself will more than pay for the manual and any tools needed to do the job. front brakes are really easy so you should be fine.
I believe it is not a spring....its just a piece of rubber. Just undo the two bolts and get a hammer and gently tap the caliper off. Just like a 2 wheel drive. Good luck!
Don't know what truck you have but I will say that on mine if you remove the slide bolts on the calipers instead of the two big bolts, you can replace the pads more easily than pulling the whole caliper.
If you don't pull the whole caliper, then how do you get the cylinders to slide back and accept the thicker, new pads? I always end up disconnecting everything to get the fluid out of the caliper to let the cylinders slide back.
You undo the bleeder screw and get a c-clamp and tighten it on the piston then the fluid comes out. Then you tighten the bleeder screw back up. Don't disconnect the caliper from the flex hose because then you for sure have to bleed the air out of the system. Good luck!
On every brake job I have done in the past six years, all I do is remove the mstr cyl cover then compress the brake piston. On everything from a 73 Chevy or 87 Toyota to my Aerostar. I do not see why a front ABS system would be different. Then again I have not done a Ford truck beyond 2000.
Don't take the large (18mm hex) bolts out. The smaller ones with the rubber compression boots on them are the ones you want to remove. Use a large flat blade screw driver to apply some pressure between the pad and the rotor to push the piston back in the caliper some. This will provide you enough slack to get the caliper off the rotor and out of the rotor's mounting bracket. Use a vise grip type c-clamp to compress the piston back into the caliper when the pads are removed. Place a rag over the master cylinder when you compress the piston to prevent the brake fluid from shooting up to the underhood paint.
