Back to my own car again, bumblebee the 1.2 8v Fiat Punto Active sport
We’ve all had the beloved noise of air escaping quickly out of your tyre’s, yet again i seem to have yet another one
Meet the stone that has written off the near new tyre due to the size, since you can only repair holes upto 6mm…. this is about 1cm wide
Since my front tyre’s were close to the limits, and 1 wont hold air, time to whip the winter rubber off and slap the much better summer tyres
Only to discover im ready for a new set of pads as there is about 2mm remaining
So while the tyres were off – it makes logical sense to just give the pads a quick change before refitting the wheels
The punto has a very quick and easy way to remove the pad, 1 R clip and 1 bar which taps out very easily with a few hammer taps
This allows the caliper to rotated on the slider, whip the pads out, return the piston to its fully retracted position, a spray clean and rub with some abrasive paper on the friction spots to allow free movement of the pads. With everything cleaned up the pads are copper greased on the friction spots and on where the caliper/piston sits on the pads using some anti-seize paste to prevent brake squeal and pads getting stuck in there runners
Everything all cleaned up – you rotate the caliper back again and insert the bar, with the locking R clip
A quick run around the edge of the disc with a blunt end to clean the scale/rust/swarf off the edge to prevent noise
The pads are ready to go 🙂
A spray of brake cleaner to remove any excess dust and finger marks the wheels are slotted back on and torqued up
Before going for a test drive, you need to press the brake pedal several times to ensure the pistons are pumped up to remove excessive room to allow a positive feel through the brake pedal and to ensure its not a spongy pedal as air managed to enter when pushing the fluid out via the bleed nipples
While servicing the pads its noted that 1 of the dust seals prevent ingress of grime/water/oil/anything off the road has split and will require replacement. If dirt was to enter it could cause the small square cut seal in the piston to leak = spongy pedal and ineffective brake pedal
As always its nice to see fairly consistent wear between all the pads, there is a slight difference, but nothing to worry about
As with any brake parts replacements its advisable to drive carefully to prevent, as there they require time to bed in
So remembering to brake a little earlier to allow them to bed in
All done for another year
