Doin my front brakes 2000 gmc 1500 what size is the torx bit I need. Thanx

 

I think its a t-55.

 

my 04 is a T55

 

Thanx I just finished, it was the t-55. Damn gm for not using a reg bolt for a socket.

 

You didn't have to take those guide pin bolts out. Next time just unbolt the entire caliper and bracket assembly by taking the two 18mm bolts.

 

You can't grease the slides, and pins if you do it that way. The pins are pretty much guaranteed to stick, and ruin the rotors if you don't take it apart, and grease everything.

 

did you have to mention greasin the pad i forgot, damn auto parts clerk for not tryin to sell me the lil grease pack

edit: just read your message over again, what do you mean by greasing the pins? i thought you meant the back of the pads at first. when i took off the torx bolt there was some grease on it. that has to be greased?

 

YES!!! the pins pull out of the rubber boots shoot some grease in there and slide them
in and out then seat the pins in the boots and you are set

 

As stated pull the pins, but it is also best to take some brake clean or something similar and clean the old grease from the pins, as they get gummed up. Even though the boots are there to help keep debris from them, brake dust, road grime, ect. combined with the old grease that tends to dry out over time will cause a situation just as what was previously stated of not allowing the calipers to float properly. Also, while you have the calipers off and the pads out, take a quick look at the piston dust boots for damage and observe the freedom of smooth movement as you compress the pistons back in when you prep them for pad installation. Either use an old pad or tool designed to compress the pistons back in straight, as to not let them **** in their bores. While you’re at it check the outward appearance of the rubber brake lines for obvious cracking or bulging. While you can not see internal damage to the hoses, if you see any damage to the outside of them you should still replace them if you haven’t already and at 11 years or so old, you probably need to. Also, not all pads are created equal in their manufacture. Some, especially if the backing plates are painted do not slide freely in the caliper and might need dressing up with a file to get the best fit. One last thing, do not apply grease to the rear of the pad. I imagine it was just a slip of the tongue and what you really meant was using an anti-squeal compound on the back side of the backing plates. Doing all this, if your other parts such as the rotors and so on are in good shape, you should end with a brake job that will last you a while.

 

Yes I meant the anti-squeal grease. An I did check the brake lines an piston boots all were in good shape. Just didn't know about greasing the pins. Will be doin that this wkend. Thanx again
