The necessary special tools and devices for
replacement of linings: a device for clamping plates
to the block, the drying chamber.
Friction pads are fixed on two ways:
bonding and priklepyvaniem.
The sequence of operations for bonding a new lining.
A. Clean the pad from dirt and remove the remnants of the adhesive before
pads on the grinding wheel or a file.
Two. Make a rough inner surface of the new pads,
(Remove the glossy layer) with a file or grinding wheel.
Three. Thoroughly degrease the outer surface of the pad.
4. Apply to the inner surface of the lining and the outer
the surface of a thin layer of adhesive pads Sun-1OT (a solution of synthetic
resins in organic solvents) and draxinfor 30 minutes
at 15 ° C.
Five. Press the parts together pressure 5.8 kgf / cm in a special
adaptation (Fig. 190) and soak in a compressed form in the drying
chamber at a temperature of (190 ± 10) ° C for 40 min, however, does not
Considering the time of heating to this temperature.
6. Cool details in compressed form to a temperature no higher than 50 ° C,
then remove the finished block with glued strip.
7. Proshlifuyte a special adaptation of the outer surface
lining, will provide the dimensions shown in Fig. 191.
With new gaskets priklepyvanii do the following.
A. Clean the pad from dirt and remove the remnants of the old glued
plates with a file or grinding wheel.
Two. Drill holes in the new lining for the rivets and tsekuyte
them with the convex side of the piece (Fig. 192). It should be
use the block as a conductor, since it contains
holes for rivets. Material rivets - brass L62.
Three. Rivet a new gasket. Riveting start with the two middle
rivets, and then put the rivets in the direction of both pairs
Before the rivet inspect the inner surface of the friction
cover and remove from it all the irregularities and burrs formed
when drilling holes and which may interfere with tight fit
lining to the shoe.
To ensure a tight priklepyvaniya lining to block
recommended to use a special clamp (Fig. 193).
Priklepyvanie lining to the brake shoe is expedient to make
on a special machine. If you need to use hand-riveting
special mandrel (Fig. 194).
4. Firmly lining to the shoe.
Close fitting caps to block the entire surface
check the probe thickness 0.18 mm, which should not be included under the
overlay on the length of 20 mm.
Five. Podshlifuyte a special adaptation of the external surfaces
linings, ensuring receipt of sizes, as shown in Fig. 191.
After grinding rivet heads should be recessed
pad to a depth of not less than 2.5 mm when measured from the outer
Dimensions brass rivets and holes for her e friction lining
Brake pads are shown in Fig. 192.
