Re: The wheels

Post by benito brz » Sat Jun 13, 2020 1:53 am

Hello everyone, I've put the bike on wheels, it looks amazing but the wheels aren't turning well, maybe because i didnt put the bearings correctly :expressionless:

Image
Image

I've put this on the bearings so they can stay in

Re: BRAKE LIQUID ATTACK !!!!

Post by benito brz » Sat Jun 13, 2020 2:14 am

Here is the front brake, i received a lot of parts and i will change the pistons

Image
Image
Image
Image
Image
Image
Image

LETS PUT SOME BRAKE LIQUID SO IT WILL FIT EASIER

Image
Image

BUT THE PAINT ON THE BRAKE CALIPER IS GOING OUT BECAUSE I'M DUMB AND I'VE JUST PUT BASIC PAINT ON IT :rage:

Image
Image

I ALSO BLOCKED THE PISTONS, THEY WONT GO OUT !!!
SO I REASSEMBLY THE MASTER VAC AND PUT SOME BRAKE LIQUID IN IT SO THE PISTONS WILL MOVE, MY FATHER WAS HELPING ME, HE DOESNT WANT THE BEAUTIFUL PAINT OF THE MASTER VAC TO BE DESTROYED SO HE PROTECTED IT WITH SOME TAPE, BUT HE BROKES THE LITTLE WINDOW WITH HIS FINGER SO ALL THE BRAKE LIQUID DESTROYED THE MASTER VAC PAINT !!!! :rage:

Image
Image
Image
Image

JUST BECAUSE I WAS BUSY FOR THIS, I ORDERED A NEW BRAKE CALIPER AND MASTER VAC IN GERMANY, SO I DO NOT HAVE TO PAINT THEM :rage:
LESSON OF TODAY: DONT BE LIKE ME

The rear brake, this time i will not disassembly the pistons or paint anything because i changed the brake caliper 2 years ago, i will clean everything and change the screws and washers.

Re: New wheels

Post by benito brz » Fri Jul 31, 2020 11:23 am

Hello everyone, i've bought some used wheels for cheap to replace my white wheels because they are too damaged to be used
but the wheels i bought on the internet are also a little damaged but its fixable, i want to paint them in white exactly like the others.
But my dad wants to take all my wheels to a guy who can fix them so i can use the white wheels and not paint again the other wheels.
I think we cant fix the white wheels but my dad wants to try, so i'm waiting for september for some news.

Here is the damage on the wheels i bought

Image
Image

And here is the white wheels, the discs aren't right when i screw them up on the wheels

Re: Rust alert !!!!!

Post by benito brz » Fri Jul 31, 2020 12:09 pm

The screws wich i had removed the rust starts rusting again, apparently putting wd40 on it is not enough, so i took all of them, clean them, and put some anti-rust on them (owatrol)

And after :sunglasses:

Wow! You have a new challenge every step of the way!

Good job working through it!

Just don't know what to say about the damage on both those sets of wheels. Doesn't make any sense to me.
